Question

If by selling a bed cover for Rs 450 the dealer loss 4% for what amount should he sell it in order to gain 20%

Answer 1

Sp = 450

Loss = 4%

Cp = 100/(100-loss%) x sp

Cp = 100/(100-4) x 450

Cp = 100/96 x 450

In order to gain 20%

Sp should be

Sp = (100+gain%)/100 x cp

Sp = (100+20)/100 x 100/96 x 450

Sp = 120/100 x 100/96 x 450

Sp = 120/96 x 450

Sp = 562.5

Hope it helps :)

Answer 2

SP=Rs 450
loss =4%
CP= 100/96 × 450

CP = RS 468.75
SP = 120/100× 468.75
= 562.5
