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: Option A

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.

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

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

For 1/4 kg = 60ps.

For 1kg = 240ps, (for 1000gms = 240ps).

For 200gms = 240/5 = 48ps (5 b/c 1000/5 =200).

For 1 kg, (250*4) = 60*4 paise.

1 kg is 5 times 200gm.

So for 200 (60*4)/5 = 48.

How we know to find direct proportion?

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

(200g/250g) * 60p = 48paise.

Arpita said: (Oct 7, 2016)  
250 g = 60 paise,
200 g = ?,
And cross multiply, you'll get 12000 = 250x,
x = 12000/250 = 48 paise.

@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.

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.
