Question

By selling a pot for 322 rupees a man gains15% . At what price should he sell it to gain 20%

Answer 1

do it like this= 322/15* 100=2146.66

then = 20%/100%*322=64.4

Answer 2

let c.p. of pot be 100.
gain =15℅
then s.p. =115
if sp is 115,then c.p=100
if sp is 322,then cp =100/115*322
=280
cp of pot=280
req.gain=20℅

if cp is 100,then sp=120
if cp is 280,then sp=120/100*280
= 336
answer is 336.
