  2. Equation (1)...X be the age of Dhoni's older brother and Y be Dhoni's age
    2/5X=Y

    Equation (2) Y+2=(1/2X+2)

    Solution

    Substituting Yin Equation =/(2)

    2/5X+2=1/2X


    4X+20=5X

    X(Age of Dhoni's older brother)=10

    Substituting X in Equation (1)/(2)

    Y(Age of Dhoni)=4

  5. Four years. His brother is 10.
    +2 years = Dhoni being 6 and his brother being 12
    -2 years = Dhoni being two and his brother being 8
