Answer 1

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the Cost Price.
• So, to find the cost price of the toy, we must use the formula of :

$\boxed{ \tt Cost \: Price = \dfrac{S.P}{(100 + Profit)} \times 100}$

By using this formula, we can find the Cost Price.

Given :

• Selling Price = Rs. 6
• Profit = 20%

To find :

• Cost Price

Solution :

We know that,

${ \tt Cost \: Price = \dfrac{S.P}{(100 + Profit)} \times 100}$

                  ${ \tt = \dfrac{6}{(100 +20)} \times 100}$

                  ${ \tt = \dfrac{6}{120} \times 100}$

                  ${ \tt = \dfrac{600}{120}}$

                  ${ \tt = \dfrac{60 \not 0}{12 \not 0}}$

                  ${ \tt = \dfrac{60}{12}}$

                  $\tt = 5$

Therefore, the correct option is (b) Rs.5.00.
