Question

On selling of fan for $ 810, Sam gains 8%. For how much did he purchase it? ​

Answer 1

Answer:

hiiii

your answer is here !

Step-by-step explanation:

SP of the fan = $ 810, gain % = 8%.

Therefore, CP of the fan = {100/(100 + gain %) × SP}

= $ {100/(100 + 8) × 810}

= $ {(100/108) × 810}

= $ 750

Hence, Sam purchased the fan for $ 750.

Answer 2

Step-by-step explanation:

Let C.P be x.

S.P= 810

Profit =8%

8% of x = 810 - x

2x/25 = 810 - x

2x = 2025 - 25 x

27x = 2025

x = 75
