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 "
