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?
(a) Rs. 22,781.25
(b) Rs. 24,150.25
(c) Rs. 28,140.50
(d) Rs. 18,000

• here given that capital increase by 50 percent every three years and we have to calculate the capital after 18 years that means every time capital increase by 50 percent for 18/3=6 times:
  so total capital=2000*((150/100)^6)
  =2000*11.390625
  =22,781.25
  so ans. is (a).

• for this we have to use PTR/100 formula.
  1st 3years--------> (2000*3*50)/100=3000,
  for next 3 year---> (3000*3*50)/100=4500,
  next 3 years -----> (4500*3*50)/100=6750,
  next 3 years -----> (6750*3*50)/100=10125,
  next 3 years -----> (10125*3*50)/100=15187.5,
  next 3 years -----> (15187.5*3*50)/100=22781.25
  
  
  so now it has become 22781.25 for 18 years.
