Question

a tricycle is sold at a gain of 15% had it been sold for rupees 108 more the profit would have been 20% find its cost price

Answer 1

Answer:

Profit = 15 %

Let the CP be x

SP = ( 1 + P/100) * CP

SP = ( 1 +15/100) * x

SP = 115/100x

SP = 23/20x

To make 20 %profit ,

SP = ( 1+20/100)* x

SP = 120/100x

SP = 6/5 x

According to given ,  23/20 x = 6/5x + 108

23/20x  -  6/5 x = 108

x /  20 = 108

x = 108 * 20

x = 2160 rs
