The average age of 12 students in a class is 20 years. When 3 new students join the class, the average age of the class increases by 1 year. What is the average age of the 3 new students?

Accepted Answer

Option D: 25. Total age of 12 students = 12 × 20 = 240 years. With 3 new students, total students = 15 and new average age = 21 years. Total age of 15 students = 15 × 21 = 315 years. Sum of ages of 3 new students = 315 - 240 = 75 years. Average age of 3 new students = 75 / 3 = 25 years.

Question 42

A shopkeeper sells two articles for Rs. 1,500 each. On the first article, he makes a 20% profit, while on the second article, he incurs a 25% loss. What is the overall profit or loss percentage on the total transaction?

Accepted Answer

Option C: 7.69% loss. Cost price of 1st article = 1500 / 1.20 = Rs. 1250. Cost price of 2nd article = 1500 / 0.75 = Rs. 2000. Total Cost Price = 1250 + 2000 = Rs. 3250. Total Selling Price = 1500 + 1500 = Rs. 3000. Total Loss = 3250 - 3000 = Rs. 250. Loss % = (250 / 3250) × 100 = 100 / 13 ≈ 7.69% loss.

Question 43

The ratio of milk to water in a container is 5 : 3. Some quantity of the mixture is removed and replaced with pure water. After this operation, the ratio of milk to water becomes 3 : 5. If the container initially had 32 litres of mixture, how much of the mixture was removed and replaced?

Accepted Answer

Option B: 12.8 litres. Initial volume = 32 L. Initial milk = (5/8) × 32 = 20 L. Let x litres of mixture be removed. Milk removed = (5/8)x. In the final mixture (total volume still 32 L), the ratio is 3:5, so final milk = (3/8) × 32 = 12 L. Therefore, 20 - (5/8)x = 12 => (5/8)x = 8 => x = 64 / 5 = 12.8 litres.

Question 44

Find the least number divisible by 2,3,5,6 and 15 which is a perfect square.

Accepted Answer

Option B: 900. LCM of 2, 3, 5, 6, and 15 is 2 × 3 × 5 = 30. To make 30 a perfect square, each prime factor must have an even exponent: 2² × 3² × 5² = 4 × 9 × 25 = 900. Thus, 900 is the least perfect square divisible by all the given numbers.

Question 45

If a number 'N' leaves a remainder 3 when divided by 7, what will be the remainder when '7N' is divided by 7?

Accepted Answer

Option A: 0. Since N = 7k + 3, multiplying by 7 gives 7N = 7(7k + 3) = 49k + 21, which is completely divisible by 7 without any remainder. Hence, the remainder is 0.

Question 46

A trader buys 100 pens at Rs.20 each. He sells 60 pens at a 10% profit and the remaining 40 pens at a 5% loss. What is the overall profit or loss percentage?

Accepted Answer

Option A: 4% profit. Total Cost Price = 100 × 20 = Rs. 2000. Profit on 60 pens = (60 × 20) × 10% = Rs. 120. Loss on 40 pens = (40 × 20) × 5% = Rs. 40. Net profit = 120 - 40 = Rs. 80. Overall profit % = (80 / 2000) × 100 = 4% profit.

Question 47

A can complete a piece of work in 12 days, and B can complete the same work in 18 days. A and B start working together, but after 3 days, A leaves the work. Immediately after A leaves, C joins B. B and C together finish the remaining work in 4 days. If C alone can complete the entire work in x days, what is the value of x?

Accepted Answer

Option A: 11.08 days. Let total work = 36 units. Rate of A = 3 units/day, Rate of B = 2 units/day. In 3 days, A and B complete (3 + 2) × 3 = 15 units. Remaining work = 36 - 15 = 21 units. B and C finish 21 units in 4 days => combined rate = 21 / 4 = 5.25 units/day. Since B = 2 units/day, rate of C = 5.25 - 2 = 3.25 units/day = 13/4 units/day. Time for C alone = 36 / (13/4) = 144 / 13 ≈ 11.08 days.

Question 48

Two pipes A and B can fill a tank in 12 hours and 16 hours, respectively. Pipe C can empty the full tank in 24 hours. If all three pipes are opened together, how long will it take to fill the tank?

Accepted Answer

Option D: 9 hours 36 minutes. Let capacity of the tank = LCM(12, 16, 24) = 48 units. Efficiency of A = +4 units/hr, B = +3 units/hr, C = -2 units/hr. Net filling rate with all 3 open = 4 + 3 - 2 = 5 units/hr. Time required = 48 / 5 = 9.6 hours = 9 hours and (0.6 × 60) minutes = 9 hours 36 minutes.

Question 49

Find the missing term in the number series.
40, 20, 20, 30, ___, 150

Accepted Answer

Option D: 60. The pattern follows progressive multiplication: 40 × 0.5 = 20; 20 × 1.0 = 20; 20 × 1.5 = 30; 30 × 2.0 = 60; 60 × 2.5 = 150. Hence, the missing number is 60.

Question 50

Find the wrong number in the following number series
729, 243, 182, 27

Accepted Answer

Option C: 182. The series follows division by 3: 729 / 3 = 243; 243 / 3 = 81 (given as 182); 81 / 3 = 27. Therefore, 182 is the wrong number in the series (should be 81).

Question 51

Select the combination of letters which, when sequentially placed in the blanks, will complete the series:
A, C, F, J, O, ___, ___, ___

Accepted Answer

Option A: U, B, J. Letter positions increase by +2, +3, +4, +5, +6, +7, +8: A (1) + 2 = C (3); C + 3 = F (6); F + 4 = J (10); J + 5 = O (15); O + 6 = U (21); U + 7 = 28 -> B (2); B + 8 = J (10). Thus, the next three letters are U, B, J.

Question 52

Find the wrong term in the given series
BDF, EGI, HJL, KMP, NPR

Accepted Answer

Option C: KMP. Each valid term consists of three letters with an interval of +2: B(2)-D(4)-F(6), E(5)-G(7)-I(9), H(8)-J(10)-L(12), N(14)-P(16)-R(18). In KMP: K(11)-M(13)-P(16), the step between M and P is +3 instead of +2 (it should be KMO). Thus, KMP is the wrong term.

Question 53

If in a certain language, DELHI is coded as WVOSR, then how will MUMBAI be coded in that language?

Accepted Answer

Option A: NFNYZR. The coding pattern uses opposite/reverse letters of the alphabet (sum of positions = 27): D<->W, E<->V, L<->O, H<->S, I<->R. Applying this to MUMBAI: M<->N, U<->F, M<->N, B<->Y, A<->Z, I<->R => NFNYZR.

Question 54

A man is facing South. He turns 90° clockwise, then 180° anticlockwise, and then 90° clockwise again. Which direction is he facing now?

Accepted Answer

Option D: South. Initial facing: South. Clockwise turns = +90° + 90° = +180°. Anticlockwise turns = -180°. Net angular rotation = +180° - 180° = 0°. Therefore, he is still facing his initial direction: South.

Question 55

Manisha starts walking from her house and walks 150m south, then she turns right and walks 80m, and then she turns left and walks 60m. She finally turns left and walks 280m to reach a school. What is the shortest distance between her house and the school?

Accepted Answer

Option C: 290m. Starting at origin (0, 0): (1) 150m South -> (0, -150); (2) Right turn (West) 80m -> (-80, -150); (3) Left turn (South) 60m -> (-80, -210); (4) Left turn (East) 280m -> (-80 + 280, -210) = (200, -210). Shortest distance = √(200² + (-210)²) = √(40000 + 44100) = √84100 = 290 meters.

Question 56

Pointing to a woman, Ram said, "She is the daughter of the only son of my grandfather."
How is the woman related to Ram?

Accepted Answer

Option A: Sister. 'The only son of my grandfather' refers to Ram's father. 'The daughter of Ram's father' is Ram's sister. Therefore, the woman is Ram's sister.

Question 57

A sum of Rs. 270 is to be divided among A, B, and C such that A gets twice as much as B, and B gets Rs. 30 more than C. What is the ratio of their shares?

Accepted Answer

Option C: 10:5:3. Let C's share = x. Then B = x + 30, and A = 2(x + 30) = 2x + 60. Sum: (2x + 60) + (x + 30) + x = 270 => 4x + 90 = 270 => 4x = 180 => x = 45. Thus, C = Rs. 45, B = Rs. 75, A = Rs. 150. Ratio A : B : C = 150 : 75 : 45 = 10 : 5 : 3 (dividing each by 15).

Question 58

If x and y are integers such that: x + y = 14 and x - y = 4, what is the value of x * y?

Accepted Answer

Option B: 45. Adding both equations gives 2x = 18 => x = 9. Substituting x = 9 into x + y = 14 gives y = 5. Therefore, x * y = 9 * 5 = 45.

Question 59

A boat can travel 30 km downstream in 2 hours and the same distance upstream in 3 hours. How long will it take the boat to travel 45 km downstream and then 30 km upstream?

Accepted Answer

Option D: None of the above. Downstream speed = 30 / 2 = 15 km/h. Upstream speed = 30 / 3 = 10 km/h. Time for 45 km downstream = 45 / 15 = 3 hours. Time for 30 km upstream = 30 / 10 = 3 hours. Total time = 3 + 3 = 6 hours. Since 6 hours is not among options A, B, or C, the correct option is 'None of the above'.

Question 60

A train 120 m long is running at a speed of 54 km/h. It takes T1 time to cross the pole and T2 time to cross the 180 m long platform. What is the difference in time (T2 - T1), in seconds, taken by the train to cross the platform and the pole?

Accepted Answer

Option B: 12 seconds. Train speed in m/s = 54 × (5/18) = 15 m/s. T1 (time to cross pole) = 120 / 15 = 8 seconds. T2 (time to cross platform) = (120 + 180) / 15 = 300 / 15 = 20 seconds. Difference (T2 - T1) = 20 - 8 = 12 seconds. (Alternatively, the difference is simply the time taken to cover the platform's length: 180 / 15 = 12 seconds).

Question 61

Operating System:
A) Links a program with subordinate interferences
B) Enables the programmer to draw a flowchart
C) Provides a layer, user friendly interface
