Let the age of sona be 5x and Sonali be 3x
after five years:-
age of sona= 5x +5
age of sonali = 3x+5
ATQ
(5x+5):(3x+5)=10:7
(5x+5)7=10(3x+5)
35x + 35=30x + 50
35x - 30x= 50-35
5x= 15
x=3
now
5x = 5(3)= 15
3x=3(3)=9
age of :-
sona= 15 years
Sonali = 9 years
after five years:-
age of sona= 5x +5
age of sonali = 3x+5
ATQ
(5x+5):(3x+5)=10:7
(5x+5)7=10(3x+5)
35x + 35=30x + 50
35x - 30x= 50-35
5x= 15
x=3
now
5x = 5(3)= 15
3x=3(3)=9
age of :-
sona= 15 years
Sonali = 9 years
