Mohan spends 23% of an amount of money on an insurance policy, 33% on food, 19% on children’s education and 16% on recreation. He deposits the remaining amount of Rs. 504 in bank. How much amount does he spend on food and insurance policy together?

 A) Rs. 2326 B) Rs. 5876 C) Rs. 1741 D) Rs. 3136

Answer & Explanation Answer: D) Rs. 3136

Explanation:

Let total amount = Rs. P

Total expenditure = (23 + 33 + 19 + 16)% of P = 91%ofP

Remaining money = (100 - 91)% of P = 9% of P

But given in the question that,

9% of P = 504

9p/100 = 504

=> P = 50400/9

=> P = Rs. 5600

Required money spent on Food & Insurance = 23 + 33 %

= 56% of 5600

= 56 x 5600/100 = 56 x 56 = Rs. 3136

 A) 23 B) 92 C) 48 D) 52

Answer & Explanation Answer: A) 23

Total number of female members = 115

Let the number of males = x

Number of females = y

=> x + y = 115  ......(1)

x + y(0.50) = 69 ......(2)

From (1) & (2), we get

0.5y = 46
