A starts a business with a capital of INR 1500/-, B joins the business 6 months later from the starts of the business and C joins the business 8 months later from the start of the business. In the end of the year their respective share in profit was in ratio 5:3:3. What is the sum of amount put in the business by B and C together
Let B joins with a capital of INR x.
∴ 1500×12 : x×6 = 5:3
3000:x=5:3
5x=9000
x=1800
B's capital = INR 1800/-
Now Let C joins with a capital of INR y.
∴ 1800×6 : y×4 = 3:3
450×6 :y = 3:3
3y = 450×6×3
y = INR 2700/-
C' capital =INR 2700/-
∴ Required sum = 1800+2700 = INR 4500/-
