Answer 1

Answer:

1. Cost of 36 stamps = Rs.27

2. No. of stamps that can be bought for Rs.60.75 = 81

Step-by-step explanation:

(Assuming that the units of monetary value is Rupees)

Cost of 15 stamps = Rs.11.25

=> Cost of 1 stamp = Rs.(11.25/15)

=> Cost of 1 stamp = Rs.0.75

=> Cost of 36 stamps = Rs.(36*0.75)

=> Cost of 36 stamps = Rs.27

Let no. of stamps that can be bought for Rs.60.75 = x

=> Cost of one stamp * No. of stamps = Rs.60.75

=> 0.75 * x = 60.75

=> x = (60.75/0.75)

=> x = 81

No. of stamps that can be bought for Rs.60.75 = 81
