Question 1 Profit Loss Discount and Value Added Tax Exercise 13.1

A student buys a pen for Rs 90 and sells it for Rs 100. Find his gain and gainpercent.

Answer:

We know that the cost price of pen = Rs 90

Selling price of pen = Rs 100

By using the formula,

Gain = selling price – cost price

= 100 – 90

= Rs 10

By using the formula,

Gain % = (gain/cost price) × 100

= (10/90) × 100

= 100/9

= 11 1/9 %

10. now we have to find the gain percent
the formula of
gain percent is gain divided by
cp into 100 now we put the values here
10 divided by cp is 90 into
