Sanjay and Komal started a business with Rs. 15000 each. After 8 months Komal withdrew Rs. 10000. If at the end of a year there was a profit of Rs. 32000. What was the share of Sanjay in the profit?

Sanjay's investment for 1 months = 15000 x 12 = Rs. 180000
Komal's investment for 1 months = 15000 x 8 + (15000 - 10000) x 4
= 120000 + 20000
= Rs. 140000
∴ Ratio between the investment of Sanjay and Komal
= 180000 : 140000 = 9 : 7
∴ Sanjay's profit = [9/(9 + 7)] x 32000 = Rs. 18000
