Ex 8.2 | Question 6

## Text Solution

What is known?

Discount percentage $$= 10\%$$

Marked price of a pair of jeans $$= \rm{Rs}\, 1450$$

Marked Price of a shirt $$= \rm{Rs}\, 850$$

What is unknown?

Amount customer has to pay for a pair of jeans and two shirts after discount.

Reasoning:

(i) MP of a pair of jeans $$=$$ CP of two jeans $$-$$ Discount

(ii) MP of a shirt $$=$$ CP of two shirts $$-$$ Discount

Adding (i) and (ii) will give the amount has to pay.

Steps:

MP of a pair of jeans $$=1450$$

MP of $$2$$ shirts $$=850\times 2= 1700$$

Total MP $$=1450+1700= 3150$$

\begin{align}\text{Discount on Total MP}&=10\% \times 3150\\& = \frac{{10}}{{100}} \times 3150\\& = 315\end{align}

The amount customer has to pay is $$1305 + 1530 =\rm{ Rs}\, 2835$$
