Question

Ashok sells a room heater for Rs. 322, gaining 1/6 of its cost price. What is his gain percent ??

Answer 1

Let a cost price be x
Profit= 1x/6
Profit= SP - CP
1x/6= Rs 322- x
1x/6+x= Rs 322
7x/6= Rs 322
x= Rs 322 ×6/7
x= 46×6= Rs 276
Gain= Rs (322-276)= Rs 46
G%= (46/276×100)%= 100/6 % or 16.66%or 16 whole 4/6 i.e., 16 whole 2/3%
Hope it helps☺
