Question

jaya baught two sarees for rs 800 each .she sold one at gain of5% and other at a loss of 4%.find her gain or loss present in whole transactions.

Answer 1

First find the gain percent i.e. 5% of 800. Whatever value u get add it to 800. That will be the gain amount she earned.
Now, take out 4% of 800. Whatever value u get subtract it from 800. Now campare the given to values that we just took out and subtract them. That will be ur answer

Answer 2

C. P. =800
Gain=5%
S.p.=105/100*800=>840

C. P. =800
LOSS=4%
S.P.=96/100*800=>768

TOTAL C. P. =800+800=>1600
TOTAL S. P. =840+768=>1608

In whole transaction there is gain
Because =S. P. >C. P.
=1608-1600=>Rs.8

Gain%=gain* 100/C.p
=8*100/1600=>0.5%
