If a quarter kg of potato costs 60 paise, how many paise will 200 gm cost?
48 paise
54 paise
56 paise
72 paise
Explanation:
Let the required weight be $ x $ kg.
Less weight, Less cost (Direct Proportion)
$\therefore$ 250 : 200 :: 60 : $ x $ $\Leftrightarrow$ 250 x $ x $ = (200 x 60)
| $\Rightarrow x $=$ \dfrac{(200 \times 60)}{250} $ |
$\Rightarrow x $ = 48.
