cent.​

Answer 1

Answer:

CASE OF COMPUTER:

C.P=32,500 RS

L%= 5%

S.P=WE HAVE TO FIND

S.P=100-L%/100×C.P

MEANS 95/100×32,500

FINALLY S.P= 30,400 RS @ COMPUTER

CASE OF MICROWAVE:

C.P=6500 P%=15%

S.P= WE HAVE TO FIND

S.P= 100+P%/100×C.P

MEANS S.P =115/100×6500

FINALLY S.P= 7475@MICROWAVE

NOW READ CAREFULLY PLEASE @REQUEST

THE AMOUNT HE PAID IN WHOLE TRANSACTION IS

32,500+6500=38,500 RS

NOW, THE AMOUNT HE GAINED BY SELLING THE ARTICLES -

30,400+7475=37,875 RS

WE OBSERVED: CP IS GREATER THAN S.P IN WHOLE TRANSACTION ,IT MEANS THIS IS LOSS

NOW LOSS%=L/C.P×100

LOSS = 38,500-37,875= 625 RS

NOW LOSS%=625/38,500×100

THATS 1.62%
