Q.1 The average weight of a group of 5 students is 45 kg. One more student joins the group and the average weight increases to 48 kg. What is the weight of the new student?

Check Solution

Ans: B

Total weight of 5 students = 5 * 45 = 225 kg. Total weight of 6 students = 6 * 48 = 288 kg. Weight of the new student = 288 – 225 = 63 kg.

Q.2 A typist can type 48 pages in 3 hours. How many pages can the typist type in 5 hours?

Check Solution

Ans: B

Pages typed per hour = 48 pages / 3 hours = 16 pages/hour. In 5 hours, the typist can type 16 pages/hour * 5 hours = 80 pages.

Q.3 P and Q together can finish a work in 12 days. P alone can finish the same work in 30 days. How many days will Q alone take to finish the same work?

Check Solution

Ans: B

Let the work done by P and Q together in one day be 1/12, and the work done by P alone in one day be 1/30. Then the work done by Q alone in one day = 1/12 – 1/30 = (5-2)/60 = 3/60 = 1/20. Therefore, Q alone can finish the work in 20 days.

Q.4 Find the average of the following numbers: 25, 35, 45, 55, 65

Check Solution

Ans: A

(25 + 35 + 45 + 55 + 65) / 5 = 225 / 5 = 45

**Q.5 The average of five consecutive even numbers A, B, C, D, and E respectively (in increasing order) is 60. What is the value of (B * D)?**

Check Solution

Ans: A

Since the numbers are consecutive even numbers, and the average is 60 (which is also the middle number, C), we can deduce the sequence: A=56, B=58, C=60, D=62, and E=64. Therefore, B * D = 58 * 62 = 3596.

Q.6 The ratio of the present ages of Ram and Shyam is 4:5. Five years ago, the ratio of their ages was 3:4. What will be the ratio of their ages after 10 years?

Check Solution

Ans: B

Let Ram’s current age be 4x and Shyam’s current age be 5x. Five years ago, Ram’s age was 4x-5 and Shyam’s age was 5x-5. According to the problem, (4x-5)/(5x-5) = 3/4. Cross-multiplying, 16x-20 = 15x-15. So, x=5. Ram’s current age is 4*5=20 and Shyam’s current age is 5*5=25. After 10 years, Ram’s age will be 20+10=30 and Shyam’s age will be 25+10=35. The ratio will be 30:35 = 6:7.
