A starts a business with Rs.3500 and after 5 months, B joins with A as his partner. After a year , the profit is divided in the ratio 2 : 3. What is B's contribution in the capital?
A. Rs. 7500 B. Rs. 8000
C. Rs. 8500 D. Rs. 9000

• Let B's capital be Rs.x
  then,
  3500*12/7x = 2/3
  or, 3500*12*3 = 14x
  x = 9000
  so option D

• Let B's capital be Rs. x.
  
  Then, 3500 x 12 = 2
  7x 3
  14x = 126000
  
  x = 9000.

• Let the profit b x times the money contributed per year.
  So, the total profit of A after a year = 3500x.
  Let the contribution of B be equal to M.
  Now, the total profit of B in 7 months = M*7/12*x.
  Therefore, (3500*x)/(M*7/12*x) = 2/3.
  M*7/12 = 3/2*3500.
  M = 12/7*3/2*3500 = 18/7*3500 = 18*500 = 9000 Rs.

• 3500*12 : x*7 = 2:3 More Share, More Profit (ie Directly proportional )
  => 3500*12 / 7*x = 2/3 => x= 9000 (Option D)
