Question

(i) Ashitosh has two daughter Sarita and Manisha. Present age of Ashitosh
in years is the nine more than that of twice the sum of Sarita and
Manisha. Five years hence the age of Ashitosh will be four more than 3/2
times the sum of the age of Sarita and Manisha. Determine the age of
Ashitosh.​

Answer 1

present let Ashutosh age=X

present Sarita and Manisha combined=y

after 5years Ashi=X+5

sari+ Mani=y+10

X+5=4+3/2(y+10)

X+5=4+3y/2+15

x-3y/2=15-5

2x-3y=10*2=20

X=9+2*y

x-2y=9

x-3y=20
