Solution
The correct option is A 155 cm
According to the given question, the measure of rain in 5 days is 250 mm.
The measure of rain in one day = 250/ 5 = 50 mm
Therefore, the measure of rain in one month, that is, 31 days = 50 × 31 = 1550 mm
To change from mm to cm, we need to divide 1550 by 10 (as 1 cm = 10 mm)
=155010
= 155 cm
Thus, the measure of rain in one month, which is 31 days, will be 155 cm.
