Question

P, Q and R are three cities. The ratio of average temperature between P and Q is 11 : 12 and that between P and R is 9 : 8. The ratio between the average temperature of Q and R
is​

Answer 1

Answer:

P : R = 9 : 8

P : Q = 11 : 12.

so, P : Q : R = (9×11) : (12×9) : (8×11)

= 99 : 108 : 88

so Q : R = 108 : 88

= 27 : 22

Q : R = 27 : 22.
