Answer 1

Step-by-step explanation:

Imagine,Sahil's present age is: x years

Sahil's mother's present age is: y years

1st equation is: y =3x

2nd equation is: (x+5)+(y+5)=66

or, x+5+y+5=66

or, x+5+3x+5=66

or, 4x+10=66

or, 4x=66-10

or, 4x=56

or, x=56/4

So, x=14

So, Sahil's present age is:14 years

So, Sahil's mother's present age is:

(14×3)=42 years

Answer 2

Answer:

Step-by-step explanation:

Solution :-

Let the present age of sahil be x

And the present age of sahil's mother be 3x

According to question,

⇒ (x + 5) + (3x + 5) = 66

⇒ x + 3x = 56

⇒ 4x = 56

⇒ x = 56/4

⇒ x = 14

The present age of sahil = 14  years

The present age of his mother = 3x = 42 years

Hence, the present age of sahil is 14 years and his mother is 42 years old.
