Question

please answer my Que with the solution

Answer 1

Let the present age of sona be 5x & Sonali be 3x .
after 5 years
sona age be = 5x+5

Sonali age be = 3x+5

5x+5/3x+5 = 10/7

7(5x+5) = 10(3x+5)

35x+35=30x+50

35x-30x= 50-35
5x=15

x= 15/5

x= 3
present age of sona = 5x=5×3=15 years

present age of Sonali=3x= 3×3=9years

Answer 2

Given ,

Ratio of ages of Sona and Sonali= 5:3

Let age of Sona be 5x years and age of Sonali be 3x years.

After 5 years ,

Age of Sona = 5x+5 years

Age of Sonali = 3x+5 years

According to the question ,

5x+5 / 3x+5 = 10/7

Solving the above equation , we get

x = 3

Hence , Ages of Sona and Sonali are 15 years (5x)and 9 years (3x) respectively.
