Question

Akhil sold two t.v for rs 9900 each, gaining 10% on one and losing 10% on the other what will he incur profit or loss? Give reason

Answer 1

profit tv sp=9900
profit percentage=10%
profit=profit%×cp÷100
let cp be 100
profit=10×100÷100=10
if cp =100 then sp= 100+10 =110
if sp=110 then cp=100
if sp=9900 then cp= 9900×100÷110=9000
loss tv sp=9900
loss percentage=10%
loss=loss×cp÷100
let cp be 100
loss=10×100÷100=10
if cp =100 then sp= 100-10 =90
if sp=90 then cp=100
if sp=9900 then cp= 9900×90÷100=8910
total cp = 8910+9000=17910
total sp =9900+ 9900= 19800
sp>cp
profit is incurred.
