If a quarter kg of potato costs 60 paise, how many paise will 200 gm cost?
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.

For 1/4 kg = 60ps.
For 1kg = 240ps, (for 1000gms = 240ps).
For 200gms = 240/5 = 48ps (5 b/c 1000/5 =200).
For 1kg = 240ps, (for 1000gms = 240ps).
For 200gms = 240/5 = 48ps (5 b/c 1000/5 =200).

Lets do it in a simple way;-
As we all knw quater means 250gm
Now 250gm potato= 60 paise
:. 1 gm of potato=60/250= 6/25 paise
so 200gm of potato= 200*6/25= 48 paise
As we all knw quater means 250gm
Now 250gm potato= 60 paise
:. 1 gm of potato=60/250= 6/25 paise
so 200gm of potato= 200*6/25= 48 paise

Quarter kg = 1/4 of 1kg=1/4*1000g=250g.
