Question
The ratio of the monthly incomes of Dinesh, Nikhil and
Rohan is 64:73:81. If Dinesh’s annual income is 10,496, what is Rohan’s annual income?Solution
The ratio of monthly incomes will be equal to annual incomes., so their annual income will be in the ratio of 64, 73 amd 81. So Let annually incomes of Dinesh, Nikhil and Rohan is 64x,73x and 81x respectively. Given, 64x = 10496 x=164 Now, Rohan’s Annual Income = 81 × 164 = 13284
