Question

A shopkeeper sold two almirahs for Rs 1500 each. on one he gained 20% profit and on the other he lost 20% find the loss or gain percent in the whole transaction.

Answer 1

Selling price of each Almirah is rs 500

for Ist Almirah

Sp = rs1500
gain = 20%

Cp=(100/100+gain% × sp)

=100/100+20 × 1500

= 100/120 × 1500

=rs1250

for second almirah

Sp = rs1500 ,Loss= 20%

Cp=(100/100-Loss% × Sp)

=100/100-20 × 1500

= 100/80 × 1500
=rs 1875

total Sp =rs (1500+1500)=rs3000

total Cp=rs(1250+1875)=rs3125

Cp>Sp i.e there is loss

Loss =rs(3125-3000)=rs125

Loss% =(loss/Cp × 100)%

=(125/3125 × 100)%

=(1 / 25 × 100 ) % = 4 %
