Salary for 1st month = 1200 + 240 = Rs 1440

a) 480

b) 240

c) 540

d) 0

Answer: (a)

Under new scheme salary for 9th and 11th week

= 2 (25 × 6 – 5 × 4 ) × 6 = Rs 1560

Now salary for 10th and 12th week = 2( 25 × 4 – 5 × 6 ) × 6

= Rs 840

Total salary for 3rd month = 1560 + 840 = Rs 2400

Under previous scheme total salary for 3rd month

= Rs 1920

Difference = 2400 – 1920 = Rs 480

Question : 5

Referring to the data given in previous question, Bankatlal's average monthly salary at the end of the first four months will be

a) 2040

b) 1830

c) 1760

d) 1680

Answer: (b)

Salary for 5th and 7th week = 2 × 7 × 20 × 6 = Rs 1680

Salary for 6th and 8th week = 2 × 3 × 10 × 6 = Rs 360

Salary for 2nd month = 1680 + 360 = Rs 2040

Similarly salary for 3rd month

= 2(6 × 20 × 6) + 2 ( 4 × 10 × 6)

= 1440 + 480 = Rs 1920

Salary for 4th month = 2(8 × 20 × 6) + 2 (0) = Rs 1920

Salary at the end of 4 months

= 1440 + 2040 + 1920 + 1920

= Rs 7320

∴ Average monthly salary = ${7320}/4$ = Rs 1830

Question : 6

My son adores chocolates. He likes biscuits. But he hates apples. I told him that he can buy as many chocolates he wishes. But then he must have biscuits twice the number of chocolates and apples more than biscuits and chocolates together. Each chocolate costs Re. 1. The cost of apple is twice of chocolate and four biscuits are worth of one apple. Then which of the following can be the amount that I spent on that evening on my son?

a) Rs 33

b) Rs 8

c) Rs 34

d) None of these

Answer: (c)

If number of chocolates is NC then those of biscuits

$N_B = 2N_C$

and number of apples i.e $N_A > 3N_C$

also, total amount spent

= $2N_A + N_C + 1/4 (2N_B) = 2N_A + 2N_C$

(note that amount of money spent is even number)

option (b) 33 = 8 + 24 + 1

but 2$N_A$ ≠ 25

option (c) is not possible

So, option (a) 34 = 8+ 24 + 2

$↙{even}2N_A, [N_A > 3N_C also]↙{satisfied}$

So, option (c) is correct
