Question

14. A shopkeeper bought two chairs for 3120. He sold one of them at a gain of 36% but the other was sold for
a loss of 15%. He found that each chair was sold for the same price.​

Answer 1

Answer:

LET CP OF ONE CHAIR=a

i.e. CP OF OTHER CHAIR=3120-a....................1

i.e. SP OF FIRST CHAIR=(a)(136/100)=136a/100

AND SP OF SECOND CHAIR=(3120-a)(85/100)=(265200-85a)/100

i.e. 136a/100=(265200-85a)/100

i.e. 136a=265200-85a

i.e. 221a=265200

i.e. a=1200=CP OF FIRST CHAIR

AND CP OF SECOND CHAIR=3120-1200=1920
