Question

by selling suger at 5.58per kg.A man loses 7 percent at what rate it must be sold in order to gain 7 percent?
​

Answer 1

Step-by-step explanation:

let the cp of per kg sugar be x

sp=100-loss%/100×cp

5.58=100-7/100×x

5.58=93x/100

x=5.58×100/93

x=6

cp of each kg sugar =6

when sold at a gain of 7%

sp=100+gain%/100×cp

sp=100+7/100×6

sp=107/100×6

sp=6.42per kg

it must be sold @ 6.42 per kg to gain 7%
