A person invests money in three different schemes for 6 years, 10 years and 12 years at 10%, 12% and 15% simple interest respectively. At the completion of each scheme, he gets the same interest. The ratio of his investment is =

a) 6 : 3 : 2
b) 2 : 3 : 4
c) 3 : 4 : 6
d) 3 : 4 : 2

Answer: a
Explanation: Let the principal in each case = 100 units
              1st part     2nd part     3rd part  
  Principal     →     100x6     100x3     100x2  
  Rate %     →     10     12     15  
  Time     →     6     10     12  
  Interest     →     60x6     120x3     180x2  
Interest is same in each, so equal the interest.
Required ratio
= 600 : 300 : 200 of sum
= 6 : 3 : 2
