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