Answers
Explanation: Temperature of Gurgaon at 9 am during a particular day = 15 degrees
Temperature of Gurgaon at 9 pm = 9 degrees
therefore, temperature reduced from 9am to 9pm = (15-9) = 6 degrees
time took to reduce = 9am to 9pm
= 12 hours
Temperature of Mumbai at 9am = 11 degrees
Temperature of Mumbai at 12 mid night = 6 degrees
therefore, temperature reduced from 9am to 12 mid night = (11-6) = 5 degrees
time took to reduce = 9am to 12 mid night
= 15 hours
That means, in Gurgaon, 1 degree is reduced in 2 hours
Whereas, in Mumbai, 1 degree is reduced in 3 hours
So we can conclude that the fall in Gurgaon is Greater.
