Q15 of 48 Page 109

Find the buying price of each of the following items when a sales tax of 5% is added on them.

(i) a towel of Rs. 50


(ii) Two bars of soap at Rs. 35 each.

(i) cost of a towel = Rs. 50

Sales tax on a towel = 5% of 50



= Rs. 2.5


sales tax on a towel = Rs. 2.5


Buying price = cost + sales tax


= 50+2.5


= Rs. 52.5


The buying price of a towel = Rs. 52.5


(ii) cost of a soap bar = Rs. 35


Cost of two soap bars = 35×2 = Rs. 70


Sales tax on a soap bars = 5% of 70



= Rs. 3.5


sales tax on a towel = Rs. 3.5


Buying price = cost + sales tax


= 70+3.5


= Rs. 73.5


The buying price of a soap bars = Rs. 73.5
