Using Alligations :Ravi lends Rs.3600 on S.I to Harsh for a period of 5 years.He lends a part of the amount at 4%interest and the rest at 6% and receives Rs.960 as the amount of interest.How much money did he lend on 4% interest rate?

1) 2800
2) 2100
3) 2400
4) 1200
5) 1000

• let x be the amount at 4% and 3600-x at 6%
  now (x*5*4/100 ) + ((3600-x)*5*6/100) = 960
  so x= 1200
