Question 4

The 2nd and 6th term of an arithmetic progression are 8 and 20 respectively. What is the 20th term?

Accepted Answer

Let the first term be a and common difference d. We have a+d=8 and a+5d=20. Solving gives d=3 and a=5. The 20th term is a+19d = 5+19(3) = 62.

Question 5

What is the effective discount on two successive discounts of 20% and 25%?

Accepted Answer

Use the successive discount formula: x + y - (xy/100). Here, 20 + 25 - (20 × 25)/100 = 45 - 5 = 40%.

Question 6

If 52 % 32 = 40, 22 % 20 = 4 then what is the value of 15 % 11 = ?

Accepted Answer

The pattern is (First Number - Second Number) × 2. For 52 % 32, (52 - 32) × 2 = 40. Thus, for 15 % 11, (15 - 11) × 2 = 8.

Question 7

What is the circumference (in cm) of a circle whose area is 616 sq cm?

Accepted Answer

Area is πr² = 616, so r² = 616 × (7/22) = 196, giving radius r = 14 cm. Circumference is 2πr = 2 × (22/7) × 14 = 88 cm.

Question 8

If for any year, the sales of a brand is more than average sales of these four brands in that year, then it gets a star. Which brand has the maximum stars?

Accepted Answer

Calculate the average sales of the four brands for each year. Compare each brand's sales to this average. Brand 4 exceeds the average in the most years, earning the maximum stars.

Question 9

If 5x - (1/2)(2x -7) = 5.5, then what is the value of x?

Accepted Answer

Expand the bracket to get 5x - x + 3.5 = 5.5. Simplifying this gives 4x = 2, which results in x = 1/2.

Question 10

A student has to secure 40% marks to pass. He gets 67 and fails by 13 marks. What is the maximum marks?

Accepted Answer

Passing marks = 67 + 13 = 80. Since 40% of the maximum marks equals 80, the maximum marks = (80 / 40) * 100 = 200.

Question 11

A, B and C can do a job working alone in 12, 16 and 24 days respectively. In how many days they can do the job if they worked together?

Accepted Answer

Total work = LCM(12, 16, 24) = 48 units. Efficiencies: A=4, B=3, C=2. Total efficiency = 4+3+2 = 9. Time taken together = 48/9 = 16/3 days.

Question 12

If an object moves in a circular path with uniform ________, its motion is called uniform circular motion.

Accepted Answer

In uniform circular motion, the object's speed remains constant while its velocity constantly changes due to the continuous change in direction along the circular path.
