Question

The cost price of a radio is ₹120.it was sold for 10%profit,find selling price

Answer 1

We know that,

S.P = Selling Price

C.P = Cost Price

$S.P = \frac{(100+Gain\%)}{100}\times(C.P)$

$S.P = \frac{(100+10)}{100}\times(120)$

$S.P = \frac{110}{100}\times(120)$

$S.P = \frac{11\cancel{0}}{10\cancel{0}}\times(120)$

$S.P =\frac{11}{10}\times(120)$

$S.P = \frac{11}{1\cancel{0}}\times12\cancel{0}$

$S.P = 11\times12$

$S.P = 132$

Therefore, S.P = ₹132.

Article was brought at ₹120 but it was sold at a cost of ₹132. Making a profit of ₹12 or 10%
