Question

Jai narayan sells two radio sets for rs 2288 each. On one he gains 10 percent and on the other he loses 10 percent. Find his gain or loss percent​

Answer 1

sp of one radio= rs 2288...

gain percent =10....

lets find cp..

10 percent gain means if cp is 100 sp is 110..

if sp is 110, cp 1000.

if sp is rs 1 ,cp =rs 100/110

• if sp is rs 2288, cp is 100/110×2288=rs 2080....

again,

sp of second radio =2288

loss % = 10%

again lets find cp,

10 % loss meana if cp is 100 sp is 90...

if sp is 90,, cp is 100

if sp rs 1 ,cp = 100/90=10/9

if sp is 2288 ,cp is 10/9×2288 = rs 2542.222

now total cp of 2 radios

2542.222

+2080

=4622.222

sp of 2 radios

2288

+2288

=4576...

it is loss.

loss = 4622.222

-4576

= 46.222

loss % loss / cp ×100

= 46.222/4622.222×100 =

lets remove decimal

46222/4522222×100=1.022108158
