40. The reduction of 30% in the price of sugar enables a person to get 20kg more on a purchase of Rs.2000. Find the reduced rate of sugar in Rs/kg. (approximately)

• Let x be the original price.
  now reduced price is 0.7x
  (2000/0.7x)-(2000/x)=20
  on solving we get.
  x= 300/7
  Hence reduced price is 0.7 * (300/7)
  Hence reduced price is Rs.30

• let the price of sugar is x rs/kg
  hence acording to qn,
  2000/(7x/10) - 2000/x = 20,
  by solving .... 7x/10=60
  i.e. the reduced rate of sugar is 60 Rs/kg.

• reduced price is 30. no problem here. actual price is x-(30x/100)=30 so, 42.857. rate= (42.857-30)/100=0.1287
