How old is dhoni now ?
Dhoni is now two fifth of his older brother’s
age and two years from now he will be half of
his older brother’s age.
Two years ago, dhoni was only one-fourth
the age of his older brother age at that time.

doni’s recent age is 4years,let dhoni=x,dhoni bro =y, so x=2/5y,after 2years x+2=1/2(y+2),=>2x+4=y+2=>y-2x=2,before 2 years x-2=1/4(y-2)=>4x-y=6 now add two equation (4x-y)+(y-2x)=8=>2x=8 so x(dhoni)=4year
