Answer 1

Answer:

Step-by-step explanation:

A shopkeeper buys 10 pair of shoes for Rs. 190 each.

He makes a profit of Rs 300 by selling all of them

To find:

At what price did he sell each pair?

Solution:

The C.P. of each pair of shoes = Rs. 190

∴ The C.P. of 10 pair of shoes = Rs. 190 × 10 = Rs. 1900

The shopkeeper makes a profit of Rs. 300 on the whole transaction

We know the formula as follows:

So, by using the formula above, we get

← the selling price of 10 pair of shoes

∴ S.P. of each pair of shoes =  

Thus, the shopkeeper sold each of the pair of shoes for → Rs. 220

Answer 2

Cost price of 10 pair of shoes = 190
Cost price for each pair of shoe = 190/10= 19 rs.

Profit on selling the 10 pair of shoes = 300 rs
Profit on selling each pair of shoe = 300/10 =30
So , the selling price of each shoe = 19+30= 49 rs.
