Question

Tick (✓) the correct answer:
If 14 kg of pulses cost Rs 441, what is the cost of 22 kg of pulses?
(a) Rs 627
(b) Rs 649
(c) Rs 671
(d) Rs 693

Answer 1

(d) Rs 693
Let Rs x be the cost of 22 kg of pulses.

Weight (in kg)	14	22
Cost (in rupees)	441	x

More quantity of pulses will cost more. Therefore, it is a case of direct proportion.

$$\begin{gathered} \mathrm{Now},\frac{14}{441}=\frac{22}{x} \\ \Rightarrow x=\frac{441\times 22}{14} \\ \Rightarrow x=693 \end{gathered}$$
