Question

33. At 3.00 AM, the temperature was 13°C below
zero but by noon it had risen to 32°C.
Therefore, the average hourly increase in
temperature was
(A) 5°C
(B) 7.5°C
(C) 45°C
(D) (1976)°C
34. If 4 out of 25 candidates failed a driving test​

Answer 1

Hours between 3A.M. and 12 noon is 9

And temperature risen from -13°C to 32°C is 32-(-13) = 32+13 = 45

now average will be 45/9 = 5

hence A is the correct answer
