Arun, Kamal and Vinay invested Rs.8000, Rs.4000 and Rs.8000 respectively in a business. Arun left after six months. If after eight months, there was a gain of Rs.4005, then what will be the share of Kamal?1). Rs.17802). Rs.13353). Rs.16024). Rs.890

Answer»

SAY P% is the rate of profit per month.

All three INVESTED for 6 months and after that, only Kamal and Vinay invested for remaining two months.

⇒ Profit share of Arun = 6 × (P% of 8000) = 480P

Profit share of Kamal = 8 × (P% of 4000) = 320P

Profit share of Vinay = 8 × (P% of 8000) = 640P

Total profit by all three in 8 months = 480P + 320P + 640P = 1440P

Given total profit = Rs.4005 ⇒ 1440P = 4005

⇒ P = 4005/1440

Profit share of Kamal = 320P = 320 × (4005/1440) = 4005/4.5 = Rs.890
