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 2

If all the 3 categories increase by same rate in 2013 over 2012 as they did in 2012 over 2011, then what will be the total approximate sales (in ‘000 units) of all the 3 categories taken together in year 2013?

Accepted Answer

Calculate the individual growth rate for each category from 2011 to 2012. Apply these respective rates to the 2012 sales figures to find 2013 sales, then sum them up to get approximately 3069.

Question 3

Question 12

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 13

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 14

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

Accepted Answer

The series follows a pattern of increasing differences: +2, +3, +4, +5. The next difference is +6, so 15 + 6 = 21.

Question 15

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 16

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?

Accepted Answer

Total cost = Rs 9000. Target SP for 10% profit = 9000 × 1.1 = Rs 9900. Remaining cotton = 500 - 10% = 450 kg. Selling rate = 9900 / 450 = Rs 22/kg.
