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.

EASIEST EXPLANATION
If 1/4kg of the potato costs 60.
Meaning 1 kg we divide 60 by 1/4 (60÷1/4),
(60 * 4/1)=240,
So 1kg costs 240,
What of 200gm.
Change 200gm to kgs. Ikg =1000gm.
So for 200gm to kgs =200 divided by 1000 (200/1000) =0.2.
So for 0.2kgs it will be 0.2 * 240 paise.
=48 paise.

This is my solution.
1kg=1000gm.
quarter 1kg =1 ÷ 4*1000=250gm.
250gm potato=60paisa.
200gm potato=?.
First of all convert gm to kg.
60paise * 1000gm ÷ 250=240kg.
1kg = 240rupee.
240rupee * 200gm ÷ 1000gm = 48paisa.
200gm = 48 paisa.
1kg=1000gm.
quarter 1kg =1 ÷ 4*1000=250gm.
250gm potato=60paisa.
200gm potato=?.
First of all convert gm to kg.
60paise * 1000gm ÷ 250=240kg.
1kg = 240rupee.
240rupee * 200gm ÷ 1000gm = 48paisa.
200gm = 48 paisa.

@Sukh.
Quarter means 25%.
The 25% price of potatoes is 60 paise.
Therefore,price of 1kg = Rs.2.40 (by solving x*25/100 = 60).
200 gm means 200/1000.
Then, price of 200 gm = 2.40*200/1000 = 48 paisa.

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

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).

250 g = 60 paise,
200 g = ?,
And cross multiply, you'll get 12000 = 250x,
x = 12000/250 = 48 paise.
200 g = ?,
And cross multiply, you'll get 12000 = 250x,
x = 12000/250 = 48 paise.

For 1 kg, (250*4) = 60*4 paise.
1 kg is 5 times 200gm.
So for 200 (60*4)/5 = 48.
1 kg is 5 times 200gm.
So for 200 (60*4)/5 = 48.
