    Let Papayas be P, Mangoes be M, Apple be A.

    Ratio of Papayas to Mangoes = 3:4 P: M = 3:4

    Papaya to Apple = 5:2 P:A = 5:2

    If Apples A = 27

    From P:A = 5:2, P:27 = 5:2

    P/27 = 5/2 Cross multiply

    2*P = 5 * 27

    P = 5*27/2 = 135/2 = 67.5

    P:M = 3:4

    67.5 : M = 3:4

    67.5/M = 3/4 Cross multiply

    4*67.5 = 3*M 270 = 3M

    3M = 270 Divide through by 3.

    M = 270/3 = 90

    Number of Mangoes = 90

    I m not sure of the answer but this is my best try

    Papaya: Mango = 3:4

    Papaya: Apple = 5:2

    Lets take no of papaya as x

    So, 5/2 = x/27

    By cross - multiplication, x = 27*5/2

    x = 67.5

    Total number of papayas = 67.5

    Lets take number of mangoes as y

    So, 3/4 = 67.5/y

    By cross multiplication, y = 90

    Therefore, total number of mangoes are 90 mangoes.
