Question

Javed sold two laptops at 23000 rupees each on one he gains 18% and on another he loses 18% what percent does he gain or lose on whole transaction​

Answer 1

Answer:

Loss%=3.24%

Explanation:

For first laptop:-

Acc. to question

%profit on first laptop=18%

profit=x*18/100=18x/100 Rs

S.P. for 1st laptop=x/1+18x/100

23000=118x/100

x=23000*100/118 Rs

x=19491.50 Rs

Therefore, C.P of 1st laptop = 19491.50 Rs

For second laptop

Acc. to question %  loss on 2nd laptop=18%

loss=x*18/100=18x/100

S.P. 2nd laptop=x/1-18x/100

23000=82x/100

x=23000*100/82

x=28048.78 Rs

C.P. of 2nd laptop=28048.78 Rs

OVERALL,

C.P of both laptop= x1+x2

=19491.50+28048.78

=47540.28 Rs

S.P. of both laptop=23000*2

=46000 Rs

Since, C.P > S.P., So there is loss

loss=C.P. -- S.P.

=47540.28-46000

loss=1540.28 Rs

%loss= loss/T.C.P.*100

=1450.28/47540.28*100

=3.24%
