Question

14. Selling price of 6 pens is equal to the cost
price of 7 pens. Find the gain per cent on
loss per cent​

Answer 1

Step-by-step explanation:

let the S.P. of 1 pen=₹1

then, SP of 7 pens =₹7

and SP of 6 pens =₹6=CP of 7 pens

hence, CP of 7 pens =₹6

since SP of 7 pens>CP of 7 pens,there is a gain

profit =₹(7 - 6)=₹1

profit %=profit /CP ×100

gain%=1/6 × 100

gain%=100/6

gain%=15.83%
