Question

The water requirement for the crops is
10 mm per day, in summer. In winter, it requires the reciprocal of the quantity needed in summer. Find how much water is needed in winter.

• A. $\frac{1}{5}$ mm
• B. $\frac{1}{10}$ mm
• C. $\frac{1}{2}$ mm
• D. 20 mm

Answer 1

The correct option is B $\frac{1}{10}$ mm

Water requirement for the crops in summer = 10 mm per day

In winter, it is the reciprocal of the quantity of water required in summer.

Reciprocal of 10 = $\frac{1}{10}$

Hence, $\frac{1}{10}$ mm of water is needed in winter.
