Question

If a quarter kg of potato costs 60 paisa, how many paisa will 200gm cost?
A.48 paisa
B.54 paisa
C.56 paisa
D.72 paisa

Answer 1

Hint:Here at first we will obtain the value of quarter kg. After that we will obtain the cost of 1gm of potato and from that we will get the cost of 200 gm of potato.

Complete step-by-step answer:
Quarter means one part out of the four equal parts of something i.e. $\dfrac{1}{4}$
We know that, 1Kg = 1000gm
Quarter of kg means, $1000gm \times \dfrac{1}{4} = 250gm$
Cost of the 250gm of potato = 60 paisa
Then the cost of 1gm of potato = $\dfrac{{60}}{{250}}$paisa
=$\dfrac{6}{{25}}$paisa
Hence the cost of 200gm potato is,
$\dfrac{6}{{25}} \times 200$
$ = 6 \times 8$(Cancelling 200 by 25 we got 8)
$ = 48$paisa
Therefore the cost of 200gm of potato is 48 paisa.

So, the correct answer is “Option A”.

Note:YWe can use alternative methods to solve this problem. Like we can convert paisa into rupee, also can convert grams into kilograms.
Quarter of 1kg $ = 1 \times \dfrac{1}{4}$$ = \dfrac{1}{4}kg$
And 200gm $ = \dfrac{{200}}{{1000}}kg = \dfrac{1}{5}kg$
Cost of $\dfrac{1}{4}$kg of potato = 60 paisa
Then the cost of 1 kg of potato = $60 \times 4 = 240paisa$
Hence the cost of $\dfrac{1}{5}$kg of potato = $\dfrac{1}{5} \times 240 = 48$paisa
That means the cost of 200 gm of potato is 48 paisa.
