Question

40 years from now a person will triple his
present age. What is his present age?
(1) 22
(2) 25
(3) 29
(4) 10​

Answer 1

Answer:

Above Given option is wrong

Correct answer is 20 year.

Step-by-step explanation:

Let the present age of person be x

After 40 years he will triple to x

i.e. 3x

then, equation is

3x = 40 + x

3x - x = 40

2x = 40

x = 20

Hence the person present age is 20 years

and after 40 year he will be 60 years which is triple to his presents age.

Final answer is 20 years.
