Answer 1

Answer:

$\huge\mathfrak\pink{Answer}$

It is mentioned that by selling a table for Rs. 850, a shopkeeper gains 15%.

We have to find how much he needs to sell it as to have an overall gain of 20%.

Suppose that the cost price of the table is Rs. c

As the shopkeeper gains 15%

The selling price of the table is 115% of c

This is equal to Rs. 850

>> 115% of c = 850

>> 1.15 c = 850

>> c = 739 Approximately

Hence the cost price of the table is Rs. 739

Now we need to find the price at which he needs to sell, as to have an overall gain of 20%

This is equal to 120% of the cost price

>> 120% of 739

>> 1.2 * 739

>> Rs. 886.8

Answer : He should sell the table at a price of Rs. 887 to have a gain of 20% or more .
