Question

Answer

And Shyam are in the ratio 4:5 respectively and the total of their incomes is Rs. 18,000, then Ram's income is Rs. 8,000 and Shyam's income is Rs. 10,000.

Explanation:

Let Ram's income be 4x and Shyam's income be 5x.

According to the problem, the sum of their incomes is Rs. 18,000.

Therefore, we have:

4x + 5x = 18000

9x = 18000

x = 2000

Hence, Ram's income is 4x = 4*2000 = Rs. 8,000 and Shyam's income is 5x = 5*2000 = Rs. 10,000.
