Question

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

Answer 1

Answer:

$150$ potatoes

Step-by-step explanation:

Since the assistant can peel $18$ potatoes in $6$ minutes, we know that he can peel $\frac{18}{6}=3$ potatoes in $1$ minute. Therefore, he will be able to peel $3*50=150$ potatoes in $50$ minutes. Hope this helps!

Answer 2

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).
