Question

5. By reduction in price by 30%, a man is able to
purchase 6 kg more sugar for Rs 400. The price
of sugar reduced per kg is​

Answer 1

Answer:

Rs.20

Step-by-step explanation:

original price: reduced price=100:70=10:7

so ratio of increasing quantity is inverse of ratio of price. i.e. 7:10 (original:new).

so 3 part gap= 6 kg..then 10 part=20kg.

so now 20 kg sugar can be bought for rs 400.

price of 1 kg now=400/20=rs. 20/kg.
