Question

ankit is now 9 years older than bobby in 10 years ankit will be twice as old as bobby was 10 years ago find the present age

Answer 1

Hiii friend,

Let the present age of bobby be X years.

Age of Ankit = (X+9) years.

Before 10 years age of bobby = (X-10) years.

After 10 years age of Ankit = (X+9+10) = (X+19) years.

According to question,

(X+19) = 2(X-10)

X + 19 = 2X- 20

2X - X = 19 +20

X = 39 years.

Age of bobby = X = 39 years.

And,

Age of Ankit = X +9 = 39 +9 = 48 years.

HOPE IT WILL HELP YOU...... :-)

Answer 2

Let,
Present age of

• bobby = x years
• ankit = (x +9) years

. =============

Age of bobby before 10 years = (x-10) years

After 10 years, according to question,

Ankit's age = 2(Bobby's age before 10 years)

x + 9 + 10 = 2(x - 10)

x + 19 = 2x - 20

19 + 20 = 2x-x

39 = x

Present age of bobby =39
Present age of ankit = (39+9)=48 years
