UP Police Constable Exam Model Paper 4

Given:
P is thrice as fast than Q
P and Q is 4 time as fast as R
Calculation:
⇒ P = 3Q ... (1)
⇒ P + Q = 4R .... (2)
By equation (1) and (2)
⇒ Q = R ..... (3)
⇒ So, P is thrice efficient as Q and R
⇒ The ratio of earning of P, Q, and R = 3 : 1 : 1
∴ The required result will be "3 : 1 : 1".
