    22

    Step-by-step explanation:

    Let Raju's age = x

    Nadia is twice as old as Raju, so her age is 2x

    Nadia is half as old as Bernard, so Bernard's age is 4x

    In 22 years' time, Bernard will be twice as old as Raju. We can write an equation to represent this.

    4x + 22 = 2 (x + 22)

    The 4x + 22 represent's Bernard's age in 22 years' time. The 2 (x + 22) illustrates that Bernard will be twice as old as Raju in 22 years' time, or in other words, Raju will be half as old as Bernard.

    Solve the equation.

    4x + 22 = 2x + 44

    2x = 22

    Since the question asks us to find Nadia's present age, and we have represented Nadia's age as 2x, we don't have to solve any further.

    Nadia's present age is 22.
