Question

On selling a fan for 880 rupees ,Anil gains 10% .For how much did he purchase it

Answer 1

Answer:

Given, Selling Price of the fan = Rs. 810, gain %=8%

Therefore, CP of the fan

=100+gain%100×SP

=100+8100×810

=108100×810

= Rs. 750

Thus, at Rs. 750, Sam purchased a fan.

Answer 2

Step-by-step explanation:

Data:

• Sp = ₹880
• P% = 10%
• CP = ?

Solution:

$\implies$ $\sf{CP= {\Large\frac{100 }{100+p \% }}×SP}$

$\implies$ $\sf{ {\Large\frac{ 100 }{100+10 }}×880}$

$\implies$ $\sf{{\Large\frac{ 100 }{ 110 }}×880 }$

$\implies$ $\sf{ {\Large\frac{ 100×88 }{ 11 }}}$

$\therefore$ $\boxed{\sf{CP= ₹800 }}$
