Question

J | ^By selling a pen for ₹289, a shopkeeper incurs a loss of 15%. At wh
0 |\| price should he sell it to earn a profit of 35%? ​

Answer 1

Answer:

sp: Rs. 289

loss%=15℅

cp = [{100/100-loss%} × sp]

= [{100/100-15} × 289 ]

= Rs. 340

then,

if he sells at profit of 35 %

cp = rs. 340

gain% = 35%

then,

sp = [{100+gain%/100} × cp ]

= [{100+35/100} × 340]

= [135/100 × 340 ]

= Rs. 459
