Solution :-
According to the question,
The sum of ages of priyanka and Deepika is 32 year
Let the ages of priyanka and deepika be x and y
Therefore,
x + y = 32 ...eq( 1 )
Now,
Priyanka is eldest to deepika by 6 years
x - y = 6. ...eq( 2 )
Take eq( 1 )
x + y = 36. ...eq( 1 )
x = 32 - y. ... eq( 3 )
Subsitute eq( 3) in eq( 2 )
x - y = 6
( 32 - y) - y = 6. [ From 3 ]
32 - y - y = 6
32 - 2y = 6
-2y = 6 - 32
-2y = -26
y = -26/-2
y = 13
Subsitute the value of y in eq( 1 )
x + y = 32
x + 13 = 32
x = 32 - 13
x = 19
Hence, The age of priyanka and deepika is 19 years and 13 years
