P,Q and R are three cities,The ratio of average temperatures between P...
Analysis:
- Let the average temperatures of cities P, Q, and R be 11x, 12x, and 9y, respectively.
Ratio between P and Q:
- The ratio of average temperatures between P and Q is 11:12.
- Therefore, we have 11x/12x = 11/12, which simplifies to x = 12.
Ratio between P and R:
- The ratio of average temperatures between P and R is 9:8.
- Substituting the value of x, we get 11(12)/9y = 9/8.
- Solving this equation, we find y = 16.
Ratio between Q and R:
- The average temperatures of Q and R are 12x and 9y respectively.
- Substituting the values of x and y, we get (12*12)/(9*16) = 144/144 = 1.
- Therefore, the ratio between the average temperature of Q and R is 1:1, which is equivalent to 22:22.
Conclusion:
- The correct answer is
none of these (d) as the ratio between the average temperature of Q and R is 1:1, not 22:27, 27:22, or 32:33.
