Answer 2

Given:

Zain sold a can of oil for RS 780 at a loss of 15% calculate his cost price?

To find:

His cost price

Solution:

The selling price of the can of oil = Rs. 780

The loss percentage = 15%

We know,

$\boxed{\bold{C.P. = \frac{100\%}{100 - L\%} \times S.P.}}$

Now, on substituting the given values in the formula above. we get

Zain's cost price of the can of oil was,

= $\frac{100\%}{100 - 15\%} \times 780$

= $\frac{100\%}{85\%} \times 780$

= $\frac{100}{85} \times 780$

= $\bold{Rs.\:917.64}$

Thus, His cost price was → Rs. 917.64.
