​

Answer 1

Answer:

Given :-

A product when it is sold for Rs 120 with a gain of Rs 20.

To Find :-

What is gain percentage.

Formula Used :-

$\longmapsto \sf\boxed{\bold{\pink{Cost\: Price =\: Sold\: Price - Profit}}}$

$\longmapsto \sf\boxed{\bold{\pink{Gain\% =\: \bigg(\dfrac{Gain \times 100}{Cost\: Price}\bigg)}}}$

Solution :-

Given :

Cost Price = Rs 120

Profit or Gain = Rs 20

According to the question by using the formula we get,

↦ $\sf Cost\: Price =\: Rs(120 - 20)$

➠ $\sf\bold{\green{Cost\: Price =\: Rs\: 100}}$

Now, we have to find the gain percentage :

Given :

Cost Price = Rs 100

Gain = Rs 20

According to the question by using the formula we get,

↦ $\sf Gain\% =\: \bigg(\dfrac{20 \times \cancel{100}}{\cancel{100}}\bigg)$

➲ $\sf\bold{\red{Gain\% =\: 20\%}}$

$\therefore$ The gain percentage is 20%.
