Answer 1

Answer:

Step-by-step explanation:

Given :-

After 12 years I shall be 3 times as old as 1 was 4 years ago.

To Find :-

• The Present Age

Solution :-

Let present age be x years

According to the question,

• ⇒ (x + 12) = 3(x – 4)
• ⇒ x + 12 = 3x – 12
• ⇒ 2x = 24
• ⇒ x = 24/2
• ⇒ x = 12 years

Present age = 12 years.

Hence, the present age is 12 years.

Answer 2

Answer:

12 years

Step-by-step explanation:

let the present age be x

age after 12 years =(x+12)

age before 4 years=(x-4)

three times old =3(x-4)

According to the question,

(x+12)=3(x-4)

x+12=3x-12

12+12=3x-x

24=2x

24÷2=x

12=x

x=12
