X, Y and Z started a business by investing Rs. 27,000, Rs. 72,000 and Rs. 81,000 respectively. At the end of the year, the profits were distributed among them. If Z’s share of profit be Rs. 36,000, then the total profit was:
Explanation:
X : Y : Z = 27000 : 72000 : 81000 = 3: 8 : 9.
so, Z’s share : Total Profit = 9 : 20.
Let the total profit be Rs. x.
Then, 9/20 * x = 36000
or x = 36000 x 20 / 9 = 80000.
