Question

P, Q and R three cities. The ratio of average temperature between P and Q is 11: 12 and that betweenP and R is 9:8. The ratio between the average temperature Q and R(a) 22.27(b) 27.22(c) 32: 33(d) none

Answer 1

the ratio of average temperature between P and Q cities=P:Q= 11:12
the ratio of temperature between P and R = P:R = 9:8
P:Q = 9 (11:12) =99:98
P:R = 11 (9:8) =99:88
Here P parts are equal
There fore Q:R =108:88
=27:22

therefore option (b) is the right answer
