Answer 2

Answer:

2 students have to eat for 8 minutes each day to consume twice the number of sweets in 20 days.

Step-by-step explanation:

let the number of sweets be x.

4 students can consume x sweets in 8 days.

2 students will consume it in 16 days.

They take 5 minutes each day to consume the sweets.

Now, if the sweets are doubled, then 2 students will take 32 days by consuming 5 minutes a day to finish all sweets.

But, we have number of days as 20.

Let the time taken be y.

ATQ:

32 × 5 = 20 × y

160 = 20y

y = 160 / 20

y = 8 minutes.

Therefore, 2 students have to eat for 8 minutes each day to consume twice the number of sweets in 20 days.
