Sachin was twice as old as ajay 10 years back. how old is ajay today if sachin will be 40 years old 10 years hence?

Answer»

Answer:

Sachin is 30 years old and AJAY is 20 years old.

Step-by-step explanation:

GIVEN : Sachin was twice as old as ajay 10 years back.

To FIND : How old is ajay TODAY if sachin will be 40 years old 10 years hence?

Solution :

Let the Sachin's age be 'x'.

Let the Ajay's age be 'y'.

According to question,

Sachin was twice as old as ajay 10 years back.

$x-10=2(y-10)$

If Sachin will be 40 years old 10 years hence.

i.e. Sachin's today age is $x=40-10=30$

SUBSTITUTE in the equation,

$30-10=2(y-10)$

$20=2y-20$

$2y=40$

$y=20$

Sachin is 30 years old and Ajay is 20 years old.
