The current age of Savan is four times the age of Akshan. 10 years from now. Savan's age will be twice the age of Akshan. What is Savan's current age ?

Options

A. 30 years
B. 20 years
C. 10 years
D. 5 years

Answer

B

Explanation

Suppose the present age of Akshan is x years. Present age of Savan = y years
According to question,
`4x=y`
or, `4x-y=0 " "` …(i)
And, `2(x+10)=y+10`
or, `2x+20=y+10`
or, `2x-y=10-20 " "` …(ii)
From equations (i) and (ii).
`x=5`
`therefore` Present ago of Savan = y
`=4x=4xx5=20` years
