Answer 1

Answer:

Let the present age of rashid's father be x

Let the present age of rashid be y

Now, a/q...

X=3y

After 5 year the sum of their age will 70

So, we have

X+5+3y+5=70

X+3y+10=70

X+3y=60

Putting 1st eqn...

X+X=60

2x=60

X=30

So, y=x/3

Y=30/3

Y=10

Answer 2

Answer:

Age of Rashid = 15 years ,

Age of father = 45 years.

Step-by-step explanation:

let the present age of rashid = x years

Then, his father's age = 3x years

and after 5 years age of rashid = ( x + 5 )years

and after 5 years age of father = ( 3x + 5 )years

According to the question

age of father after 5 years = 2× after 5 years age of his son.

3x + 5 = 2x ( x + 5 )

3x + 5 = 2x + 10

3x – 2x = 10 – 5

x = 5

Thus, the present age of rashid = 3x

= 3×5

= 15 years

the present age of his father = 3×15

=45 years
