than his son. What is the current age of father (in years)?

(a) 34
(b) 42
(c) 44
(d) 45
A 80

Answer 1

Answer:

(c) 44

Step-by-step explanation:

let the age of son be x therefore father's age is 2x

given 20 years ago the father was 12 times

therefore (2x - 20) = 12 (x-20)

2x-20= 12x -240

240-20=12x-2x

220=10x

x=22 ( this is son's age)

2x = 2×22= 44 (this is father's current age)

Answer 2

Answer:

44 years

Step-by-step explanation:

Let the age of son be x years and father be 2x years.

20 years back their ages were x-20 and 2x-20.

As per the given condition,

2x-20=12(x-20)

=2x–12x=20–240

=-10x =–220

= x = 220/10

x=22

2x=44
