Question

Aarav is 7 years older than Bhargav who is twice as old as Sachin.
The total of the ages of Aarav, Bhargav and Sachin is 87.
How old is Sachin?

Answer 1

Let Sachin's age be X

Then by given conditions,
Bhargav's Age=2X ( given that Bhargav is twice as old as Sachin)
Aarav's Age =2X+7(given that Aarav is 7 years older than Bhargav)

Then,
(2X+7)+2X+X=87
2X+2X+X+7=87
5X+7=87
5X=87-7=80
X=80/5=16

Therefore Sachin's Age=16

Answer 2

Let the age of Sachin be x
Then by given conditions,
Bhargav's age= 2x ( given that Bhargav is twice as old as Sachin)
Aarav's age = 2x+7 (given Aarav is 7 years older than Bhargav)

Then,
(2x+7)+2x+x=87
2x+7+2x+x=87
2x+2x+x+7=87
5x+7=87
5x=87-7=80
x=80/5=16

Therefore Sachin's Age=16
