Question

ben is 4 times as old as is ishaan. 6 years ago, ben was 6 times as old as ishaan. how old is ishaan now?

Answer 1

15 years

Explanation:

Let Ishaan's age = x years

Ben is 4 times as old as Ishaan.

Hence, Ben's age is 4*x years

6 years ago,Ishaan's age was (x-6) years.

6 years ago,Ben's age was (4x-6) years.

6 years ago, ben was 6 times older than ishaan.

=>
`\[(4x-6) = 6*(x-6)\]`

=>
`\[4x-6 = 6x-36\]`

=>
`\[6x-4x = 36-6\]`

=>
`\[2x = 30\]`

=>
`\[x = (30)/(2)\]`

=>
`\[x = 15\]`
