Question

a fan is sold for $ 650.the gain is one-fourth of the cost price og the fan . find the gain per cent

Answer 1

Hi friend
--------------
Your answer
-------------------

Selling price = 650$

Let the cost price be x.

Profit = ¼ × x

Then,
-----------

Selling price - Cost price = Profit

⇒ 650 - x = ¼ × x

⇒650 = x + x/4

⇒ 650 = 5x/4

⇒ x = (650 × 4)/5

⇒ x = 520

Gain = 520/4 = 130$

So,
------

Gain% = (gain/cost price × 100)

= (130/520 × 100)%

= 25%
