Madhya Pradesh Police Exam Model Paper 2

As P : Q = 3 : 4 and Q : R = 6 : 7
To find the ratio of P : Q : R, we will make Q equal in both ratios
∴ multiplying first ratio by 3 and second ratio by 2
∴ P : Q = 9 : 12 and Q : R = 12 : 14
∴ P : Q : R = 9 : 12 : 14
Now the share of Q can be given as
$=12/\left(9+12+14\right)\times 700$
$=\left(12/35\right)\times 700$
= Rs. 240
