    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the present age of ‘Amisha’ and ‘Bhuvan’ be ‘a’ years and ‘b’ years, respectively. So, 2 × (b – 5) = a Or, b = {(a + 10)/2} ………. (I) Also, b = 0.8 × (a – 5) Or, b = 0.8a – 4 ………… (II) Using Equation (I) and (II), we have; 2 × (0.8a – 4) = a + 10 Or, 1.6a – 8 = a + 10 Or, 0.6a = 18 So, a = 30 So, present age of ‘Amisha’ = 30 years
