years as he is now. How old is he at
present?
explain plz.​

Answer 1

This question is an algebra question and it tests the ability to interpret sentence statements and translate them into number statements, and then solve the unknown variable.

Define x:

Let Riaz be x years old.

In 45 years time:

*We add 45 to his present age.

Riaz will be (x + 45) years old.

Given that he will be 4 times as old as he he now:

*We multiply 4 times to his present age.

x + 45 = 4x

3x = 45

x = 15 years old

Answer: He is 15 years old now.

Answer 2

Answer:

present age of riaz is 15 years.

Step-by-step explanation:

Let the present age of Riaz be m.

After 45 years, age of riaz = m + 45

4 times the age of Riaz = 4m

According to the question,

Riaz would be 4 times as old in 45 years as he is now.

m + 45 = 4m

=> m - 4m = -45

=> -3m = -45

=> m = 45/3

=> m = 15

Therefore, present age of riaz is 15 years.
