Let the age of father be x years

Let the age of one of his children be y years and age of other children be z years

From given information,

x=2×(y+z)...(1)

After 20 years,

(x+20)=(y+20)+(z+20)...(2)

Substituting value of (1) in (2), we get

2×(y+z) +20=y+z+40

2y+2z−y−z=40−20

y+z=20...(3)

Substituting value of (3) in (1), we get

x=2×(20)

⇒x=40

Answer 2

Answer:

The answer is 60° right from north

Explanation:

First the car turns 20° to left.

Then it turns 80° but on the opposite side i.e. right. That means 100° towards the left.

So we get total deviation of 120°  left from north or we can say 60° right from north
