Question

a scooter was sold for rupees 21000 and gain of 5% was made what would be gain percent if it was sold for rupees 45000​

Answer 1

Given

S.P ( selling price) of scooter = 21000.

Profit % = 5%

So , C. p ( cost price)

CP =

$\frac{100}{100 + profit\%} \times sp$

$\frac{100}{100 + 5} \times 21000$

$cp = 20000$

Now, if we sell the scooter for 45000 rs. Then the profit% is:

$profit\% = \frac{profit}{cp} \times 100$

$profit\% = \frac{21000 - 20000}{20000} \times 100$

profit% = 125%

So we will get the profit of 125% , if sp is 45,000rs

Hope it may help you
