Q.2 Find the H.C.F. of 120, 144, and 216.

Check Solution

Ans: C

Prime factorize each number: 120 = 2^3 * 3 * 5; 144 = 2^4 * 3^2; 216 = 2^3 * 3^3. The HCF is found by taking the lowest power of common prime factors: 2^3 * 3 = 24

Q.3 The value of log2(1/32) is

Check Solution

Ans: B

log2(1/32) = log2(2^-5) = -5

Q.4 If the G.C.D. of x^2 + (q + 2)x + 1 and x^2 + qx + 1 is (x + 1), then the value of q is

Check Solution

Ans: C

Since (x+1) is a common factor, both polynomials must equal 0 when x = -1. For the first polynomial: (-1)^2 + (q+2)(-1) + 1 = 0 => 1 – q – 2 + 1 = 0 => q = 0. For the second polynomial: (-1)^2 + q(-1) + 1 = 0 => 1 – q + 1 = 0 => q = 2. The second polynomial helps to calculate the correct q value.

Q.5 A box contains red, blue, and green marbles in the ratio 3:4:5. The total number of marbles in the box is 60. The number of blue marbles is

Check Solution

Ans: C

Let the number of red, blue, and green marbles be 3x, 4x, and 5x respectively. The total number of marbles is 3x + 4x + 5x = 12x. We are given that 12x = 60. Therefore, x = 5. The number of blue marbles is 4x = 4 * 5 = 20.

Q.6 If the HCF and LCM of two numbers are 12 and 144 respectively, and one of the numbers is 36, then the other number is

Check Solution

Ans: C

We know that product of two numbers = HCF * LCM. Let the other number be x. So, 36 * x = 12 * 144. Thus x = (12 * 144) / 36 = 48.

Q.7 A shopkeeper has a mixture of 40 litres of milk and water. The mixture contains 30% milk and the rest is water. If the shopkeeper adds 10 litres of milk to the mixture, what is the percentage of water in the new mixture?

Check Solution

Ans: A

Milk in the original mixture = 40 * 0.30 = 12 litres. Water in the original mixture = 40 – 12 = 28 litres. After adding 10 litres of milk, the total milk becomes 12 + 10 = 22 litres. The total volume of the new mixture = 40 + 10 = 50 litres. Percentage of water in the new mixture = (28/50) * 100 = 56%.

Q.8 Write √432 as a mixed surd.

Check Solution

Ans: A

√432 = √(144 * 3) = √144 * √3 = 12√3

Q.9 A vessel contains 40 litres of milk. 4 litres of milk is taken out and replaced with water. This process is repeated two more times. What is the quantity of milk left in the vessel?

Check Solution

Ans: B

Milk left after 1st operation = 40 * (1 – 4/40) = 36 litres. Milk left after 2nd operation = 36 * (1 – 4/40) = 32.4 litres. Milk left after 3rd operation = 32.4 * (1 – 4/40) = 29.16 litres.

Q.10 A pump can fill a tank in 12 hours. Due to a leak in the tank, it takes 18 hours to fill the tank. If the leak is open, how long will it take for the leak to empty a full tank?

Check Solution

Ans: C

Let the pump’s filling rate be 1/12 of the tank per hour. Let the leak’s emptying rate be 1/x of the tank per hour. The combined rate when both are active is 1/18 of the tank per hour. Therefore, 1/12 – 1/x = 1/18. Solving for x: 1/x = 1/12 – 1/18 = (3-2)/36 = 1/36. Thus x = 36.

Q.11 A train travels at 60 kmph for 2 hours and then at 80 kmph for 3 hours. A bus travels at 40 kmph for 4 hours and then at 50 kmph for 2 hours. Find the ratio of the total distances covered by the train and the bus.

Check Solution

Ans: B

Distance covered by train = (60 * 2) + (80 * 3) = 120 + 240 = 360 km. Distance covered by bus = (40 * 4) + (50 * 2) = 160 + 100 = 260 km. Ratio = 360:260 = 18:13

Q.12 A multiple-choice quiz has 5 questions. Each question has 4 answer choices. In how many ways can a student attempt the quiz, assuming they must choose one answer for each question?

Q.14 A baker used 2 ½ cups of flour for a cake and 1 ¾ cups of flour for cookies. He then decided to make bread, using 3 ¼ cups of flour. If he had a 9-cup bag of flour initially, how much flour does he have remaining?

Check Solution

Ans: A

Total flour used = 2 ½ + 1 ¾ + 3 ¼ = 2.5 + 1.75 + 3.25 = 7.5 cups. Remaining flour = 9 – 7.5 = 1.5 cups = 1 ½ cups.

Q.15 The sum of three numbers is 12. The sum of their squares is 50. What is the sum of the products of the numbers taken two at a time?

Check Solution

Ans: D

Let the three numbers be x, y, and z. We are given: x + y + z = 12 x^2 + y^2 + z^2 = 50 We want to find xy + yz + xz. We know that (x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + yz + xz) Substituting the given values: 12^2 = 50 + 2(xy + yz + xz) 144 = 50 + 2(xy + yz + xz) 2(xy + yz + xz) = 144 – 50 2(xy + yz + xz) = 94 xy + yz + xz = 94 / 2 xy + yz + xz = 47

Q.16 A clock strikes once at 1 o’clock, twice at 2 o’clock, thrice at 3 o’clock, and so on. How many times does it strike in a day?

Check Solution

Ans: C

The clock strikes a total of 1+2+3+…+12 times in 12 hours. The sum of an arithmetic series is n(n+1)/2, where n is the number of terms. So, (12*13)/2 = 78. In a day (24 hours), it will strike twice this amount. Thus, 78*2=156.

Q.17 A shopkeeper buys 20 articles for Rs. 120 and sells them at a profit of 25%. What is the selling price of each article?

Check Solution

Ans: B

Cost price of 1 article = 120/20 = Rs. 6. Profit = 25% of 6 = 1.50. Selling price of 1 article = 6 + 1.50 = Rs. 7.50

Q.18 A boat travels 40 km upstream in 4 hours and the same distance downstream in 2 hours. What is the speed of the boat in still water in kmph?

Check Solution

Ans: B

Let the speed of the boat in still water be ‘x’ kmph and the speed of the stream be ‘y’ kmph. Upstream speed = x – y; Downstream speed = x + y Distance = Speed x Time 40 = (x – y) * 4 => x – y = 10 40 = (x + y) * 2 => x + y = 20 Adding both equations: 2x = 30 => x = 15

Q.24 A ship sails 120 km east, then 90 km south. It then changes direction and travels 120 km west. Finally, it heads north and arrives at its destination. What is the straight-line distance from the starting point to the destination?

Check Solution

Ans: A

The ship moves 120 km east and 120 km west, effectively canceling out the east-west movement. It moves 90 km south. Therefore, the final straight-line distance is simply the distance traveled south which is 90 km.

Q.25 Given signs signify something and on that basis, assume the given statements to be true and find which of the two conclusions I and II is/are definitely true. “%” denotes “less than” “>”denotes “greater than“ “=” denotes “equal to“ “@” denotes “not equal to“ “#’’ denote “ greater than or equal to” “*” denote “not less than” Statements A*B, B@C, C#D Conclusions I. A>D II. A@C

Check Solution

Ans: C

A*B => A is not less than B => A >= B B@C => B is not equal to C => B != C C#D => C is greater than or equal to D => C >= D From the statements, we cannot definitively say if A>D is true (I) or not. Also, B!=C. Since A>=B, A cannot be definitely equal to C (II).

Q.27 Find the next number in the given number series : 7, 18, 34, 55, ……

Check Solution

Ans: A

The difference between consecutive numbers increases by 3, then 4, then 5 etc. 18-7=11, 34-18=16, 55-34=21. 11+5=16, 16+5=21, so next should be 21+6=27. 55+27=82. However this pattern is wrong. So another approach 7+11=18, 18+16=34, 34+21=55. Difference between 11,16,21 is 5. So next difference should be 21+5+6=27. So, next number will be 55+27=82. None of the options are correct. Another method: 7 + (1×11) = 18 18 + (2×8) = 34 34 + (3×7) = 55 55 + (4×6) = 79 None of the options is correct
