If a quarter kg of potato costs 60 paise, how many paise will 200 gm cost?
48 paise
54 paise
56 paise
72 paise
Answer: Option
Explanation:

Let the required weight be x kg.

Less weight, Less cost (Direct Proportion)

250 : 200 :: 60 : x       250 x x = (200 x 60)

x= (200 x 60)
250

x = 48.

60/250*200 = 48.
250 = 1/4 quarter.
