Question
The following statements (P, Q) are derived on the basis of precipitaiton values from the mass curve of rainfall of a self-recording rain gauge, given in the table. Identify the correct statement(s) and select the most appropriate option.
P. The intensity of rainfall during the time interval (15 to 30 min) is more than the intensity of rainfall during the time interval (75 to 90 min).
Q. There is no rainfall during the time interval (30 to 45 min).
A.
P only
B.
Both P and Q
C.
Q only
D.
Neither P nor Q
Answer ( Option C)

Q only

Solution

From the above table, it has been observed that
(i) The intensity of rainfall during the time interval (15 to 30 min) is 0.6 mm/min, which is less than the rainfall intensity during the time interval (75 to 90 min) i.e. 0.67 mm/min. 
(ii) The rainfall during the time interval (30-45) is 0. 
So, only statement Q is correct.
