Two unemployed young men decided to start a business together. They pooled in their savings, which came to Rs. 2,000. They were both lucky, their business prospered and they were able to increase their capital by 50 per cent every three years. How much did they have in all at the end of eighteen years?
option
(a) Rs. 22,781.25
(b) Rs. 24,150.25
(c) Rs. 28,140.50
(d) Rs. 18,000

• answer is (a).
  here p=2000,r=50% and time duration is 18/3=6 because money is increasing every three year gence number of attempt to increase money is 6.
  now A=P{(1+r/100)pow(6)}
  =2000{(1+50/100)pow(6)}
  =22781.25
