  1. If P : Q : = 8 : 15 and Q : R = 3 : 2, then find P : Q : R
    1. 8 : 15 : 7
    2. 7 : 15 : 8
    3. 8 : 15 : 10
    4. 10 : 15 : 8
    5. None of the above
Correct Option: C

Given that, P : Q = 8 : 15, Q : R = 3 : 2
P : Q : R = (8 x 3) : (15 x 3) : (15 x 2) = 24 : 45 : 30

∴ P : Q : R = 8 : 15 : 10
Here, consequent of first ratio should be equal to the antecedent of second ratio.
