: 5 and the ratio of Ravenna's income in the year 2018 to that in 2017 is 3:2. If Rs.
10242 is the sum of the income of Asha and Ravenna in the year 2018, then find
the income of Ravenna in the year 2017?​

Answer 1

Answer:

Rs. 4552

Step-by-step explanation:

Let the income of asha be 3x and 5x respectively.

Let the income of ravenna be 3y and 2y respectively.

Since the ratio of their income in the year 2017 was 5:4.

5x : 2y = 5 : 4

2x = y

The sum of their incomes in 2018 is Rs.10242

3x + 3y = 10242

9x = 10242

x = 1138 and y = 2276

Ravenna's income for the year 2017 = 2y = Rs.4552.
