Question

If 48 bags of paddy costs ₹16,800 then find the cost of 36 bags of paddy.

Answer 1

Total cost of paddy is directly proportional to the number of paddy bags.

Total cost of paddy bags ∝ Number of bags

$\Rightarrow \frac{\text{Total cost of 48 bags}}{\text{Total cost of 36 bags}}=\frac{48}{36}$

$\Rightarrow \frac{₹16,800}{\text{Total cost of 36 bags}}=\frac{4}{3}$
$\Rightarrow \text{Total cost of 36 bags}=\frac{₹16,800\times 3}{4}$
$\Rightarrow \text{Total cost of 36 bags}=₹4,200\times 3$
$\Rightarrow \text{Total cost of 36 bags}=₹12,600$
