Let Manju's age be x.
and Sunita 's age be y.
Then , According to question.
x = 3 + y. --------- eq. ( i )
&
x - 6 = 4 ( y - 6 ) --------- eq. ( ii ) .
⇒ x - 6 = 4y - 24. ---------- eq. ( iii ).
Now, putting eq. (i) in eq, ( iii ).
x - 6 = 4y - 24
⇒ 3 + y = 4y - 24
⇒ 4y - y = 3 + 24
⇒ 3y = 27
⇒ y = 9.
Hence, x = 3 + y
= 3 + 9 = 12.
x = 12 ; y = 9.
Therefore, Manju's present age is 12 years and Sunita's present age is 9 years.
and Sunita 's age be y.
