Question 1

If 19 + 2 x 2 + 3 = 369 and 23 + 2 x 6 + 2 = 565, then 7 + 3 x 11 + 3 = ?

Accepted Answer

The hidden pattern is A + B x C + D = A^B + C^D. Thus, 7^3 + 11^3 = 343 + 1331 = 1674.

Question 10

If x2 + (1/x2) = 1, then what is the value of x48 + x42 + x36 + x30 + x24 + x18 + x12 + x6 + 1?

Accepted Answer

Given x² + 1/x² = 1, we get x⁴ - x² + 1 = 0. Multiplying by (x² + 1) gives x⁶ + 1 = 0, so x⁶ = -1. Pairing consecutive terms gives 0, leaving only the final 1.

Question 11

A man has 3 sons, 2 daughters and a wife. They divided a sum of Rs 19000 among themselves such that each daughter got 1.5 times the amount received by each son and his wife received 600 less than each son. What is the total amount (in Rs) received by the 3 sons together?

Accepted Answer

Let each son get x. Daughters get 1.5x each, wife gets x - 600. Total: 3x + 2(1.5x) + (x - 600) = 19000. 7x = 19600, so x = 2800. Three sons get 3x = 8400.

Question 12

In the following question, select the missing number from the given series. 1, 3, 6, 10, 15, ?

Accepted Answer

Question 13

What is the area (in sq cm) of a regular hexagon of side 14 cm?

Accepted Answer

The area of a regular hexagon is given by the formula (3√3/2)a². Substituting a = 14 cm, we get (3√3/2) × 196 = 294√3 sq cm.

Question 14

A trader buys 500 kgs of cotton for Rs 9,000. 10% of this cotton is spoiled due to rain. At what rate (Rs/Kg) should he sell the rest to earn 10% profit?
