Question
Lalit buys wheat at Rs. 20/kg and puts a price tag on it
so as to earn a profit of 30%. However, his faulty balance shows 1000 gm when it is actually 600 gm. What is his actual approximate gain percentage?Solution
C.P of 1000 gm = Rs. 20 M.P of 1000 gm = Rs. 26 S.P of 600 gm = Rs. 26 ( because his balance shows 600 gm when it is actually 1000 gm ) C.P of 600 gm =20/1000 × 600 = Rs. 12 ( because C.P of 1000 gm is Rs. 20 )  Profit = 14/12 × 100 = 116.66%
