Question

Kewal sell two tape recorders at the same price. On one, he gains 10 % and on the other loses 10%. The total gain or loss in the transaction is?​

Answer 1

Answer:

1%

Step-by-step explanation:

when sp is same and loss and gain %same

total loss% = l^2/100 = 10×10/100 =1%loss

or

let sp1=sp2=100

g1=10%

cp1=sp1/(1+g1%)

=100/(1+10%)=100/1.1=90.91

cp2=100/(1-10%)=100/0.9=111.11

total cp=202.02

total sp=100+100=200

loss% = cp-sp/cp =(202.02-200/202.02)×100

=1%

hope this helps
