A invested certain amount.After 5 months,B and C joined A with certain amount.The ratio of investment is 7:14:18.C's annual share is
Rs 750 more than A's annual share.Find the annual profit?

• 5500 Rs.
  
  Investment of A is for 12 months, B for 7 months & C for 7 months. So actual ratio of investment of A:B:C=12*7 :7*14 :7*18
  =42 :49 :63
  If total profit =P, then C's share - B's share=750 or
  [p*63/(42+49+63)]-[p*42/(42+49+63)]=750
  On solving, p=5500

• Pl. read " C's share - A's share=750 " in my earlier solution instead of " C's share - B's share=750 "

• A=7x
  B=14x
  C=18x
  7x*12:14x*7:18x*7
  After solving ( 84:98:126 -> 42:49:63 -> 6:7:9)
  6:7:9
  Total profit =x
  C-A share=750
  (9*x/15)-(6*x/15)=750
  9x-6x=750
  x=250
  
  A=6*250=1500
  B=7*250=1750
  C=9*250=2250
  Total. = 5500
