Question

An assistant cook peeled 18 potatoes in 6 minutes. At this rate, how many potatoes can he peel in 50 minutes?

Answer 1

snog used unitary method to find the answer.

ALITER:-

Given,

Potatoes peeled in 6 minutes = 18

Let, potatoes cooked in 50 minutes = k

Here, more the time passes, the more the assistant peels potatoes.

∴ It is a case of direct variation,

where,

x/y = k (constant)

So, 18/6 = k/50 (potatoes peeled/time)

⇒ k = 3 × 50 = 150 (answer).

Answer 2

`150` potatoes

Explanation:

Since the assistant can peel
`18` potatoes in
`6` minutes, we know that he can peel
`(18)/(6)=3` potatoes in
`1` minute. Therefore, he will be able to peel
`3*50=150` potatoes in
`50` minutes. Hope this helps!
