Question

 In a business, A invests Rs 50000 for 6 months, B Rs 60000 for 4 months and C, Rs 80000 for 5 months. If they together earn Rs 18800 find the share of each.

Answer 1

A's 6 months investment = ₹50000
∴ A's 1 month investment
= ₹50000 x 6
= ₹300000
B's 4 months investment = ₹60000
∴ B's 1 month investment
= ₹60000 x 4
= ₹240000
C's 5 months investment = ₹80000
∴ C's 1 month investment
= ₹80000 x 5
= ₹400000
∴ Ratio between their investments
= 300000 : 240000 : 400000
= 30 : 24 : 40
Sum of ratios = 30 + 24 + 40 = 94
Total earnings = ₹18800

∴ A's share = `(30)/(94) xx 18800` = ₹6000

B's share = `(24)/(94) xx 18800` = ₹4800

C's share = `(40)/(94) xx 18800` = ₹8000.
