Question

After 12 years, a man's age will be four times that of his 12 years ago, then his present age is

(a) 15 (b) 20 (c) 25 (d) 30​

Answer 1

$\huge\mathfrak{\red{Answer}}$

➡ b) 20 years

Step-by-step explanation:

let the present age be x

So, His age

After 12 years = x + 12years

&

12 years ago = x-12years

According to the question,

x+12=4(x-12)

=> x+12=4x-48

=> -3x= -60

=> x = 20

Hence, the present age is 20years.
