Answers
Answer:
36 years.
Step-by-step explanation:
Let :
Present age of Banu be a ( in years )
Present age of Varun be 3a ( in years ) { since varun's age is thrice of banu's age }
4 years ago :
Age of banu = present age - 4
= a - 4
Age of varun = present age - 4
= 3a - 4
According to the question: 4 years ago varun's age was four times of banu's age.
= > varun's age = 4 x banu's age
= > 3a - 4 = 4( a - 4 )
= > 3a - 4 = 4a - 16
= > 16 - 4 = 4a -3a
= > 12 = a
= > 12 x 3 = 3 x a
= > 36 = 3a
= > 36 = Varun's present age
Hence, varun's present age is 36.
Answer:
Varun is 36 years old.
Step-by-step explanation:
Given :
Varun is thrice as old as Banu
4 years ago = Varun was 4 times Banu
To find :
The present of Varun
Solution :
Let the present ages be -
- Banu as y
- Varun as 3y
Ages 4 years back -
- Banu = (y - 4)
- Varun = (3y - 4)
⇒ (3y - 4) = 4(y - 4)
⇒ 3y - 4 = 4y - 16
⇒ 3y - 4y = - 16 + 4
⇒ - y = - 12
⇒ y = 12
Banu = 12 years old
Varun's age -
⇒ 3(12)
⇒ 36
Therefore, Varun is 36 years old.
