Mr. Nair's monthly salary is Rs.22,500. He took a loan of Rs.30,000 on simple interest for 3 years at the rate of 5 p.c.p.a The amount that he will be paying as simple interest in 3 years is what percent of his monthly salary?

Answer: (c)

SI = ${30,000 × 3 × 5}/100$ = 4500

x% of 22,500 = 4500

$x = {4500 × 100}/{22,500}$ = 20%

Suppose price of the printer = P

Total cost of 60 computers = 180 P

Total cost of 20 printers = 20 P

∴ Total cost of the purchase = 200 P

Thus total cost of the printers is 10% of the total cost.
