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​

Answer 1

= PR-PQ

= 9:8-11:12

= 9/8-11/12

= 27-22/24

= 5/24

= 5:24

Answer 2

Answer:

answer should be 27/22=q/r

Step-by-step explanation:

because wkt,

p/q=11/12 and..........................eq 1

p/r=9/8 .....................................eq2     <given in question>

multiply eq1 by 9 and eq 2 by 11

we get that p/q=99/108 and p/r=99/88

and by comparing this we can say that q/r=108/88

this is equal to 27/22
