    Explanation :
    X = 37*40 = 1480
    X = 38*41 = 1558
    T age = 1558 – 1480 = 78
    Aftr 2 yrs = 78+2 = 80

    P = 2S
    2s+8/s+8 = 22/13
    26s+104 = 22s+176
    4s = 72
    S= 18yr

  3. The ratio between the present ages of X and Y is 4:9 respectively. 2yrs from now, Y’s age will become twice the age of X.What was the difference between their ages five yrs ago ?

    Explanation :
    4x+2/7x+2 = ½
    8x+4 = 9x+2
    x = 2
    x:y = 8:18
    5 yrs ago = 3:13
    D = 13-3 = 10

    M = 24 – 9 =15
    D – M = 24
    D – 15 = 24
    D = 24+15 = 39
    15:39 = 5:13
    X = 13

    2N = 4
    N =4/2
    N = 2yrs
    A = 3*2 = 6yrs

    Age of Balu = A-3
    Jaswanth’s age = 6
    Balu’s Age = 4* J’s age
    i.e., A – 3 = 4 x 6
    X = 24 + 3 = 27
    Hence, Ashok’s age = 27 – 6 = 21

    X+x+3+x+6+x+9+x+12 = 50
    5x+30 =50
    X = 50-30/5 = 20/5 =4
    4+12 = 16
