Question

40 kg of wheat flour is needed for a family of 4 members. How many kgs of the same will be required if the number of members increases by 10.

• A. 140 kg
• B. 120 kg
• C. 160 kg
• D. 100 kg

Answer 1

The correct option is A 140 kg

Given, 4 members require = 40 kg of wheat flour
Since, number of members increases by 10
So number of members in the family now = 4 + 10 = 14
Let, 14 members require d kg of wheat flour

Writing in Proportion form, we have
4 : 40 :: 14 : d

Product of means = Product of extremes
$\Rightarrow$ 40 $\times$ 14 = 4 $\times$ d
$\Rightarrow$ d = $\frac{40\times 14}{4}$
$\Rightarrow$ d = 140

So, 14 members will require 140 kg of wheat flour.
