Question: A certain animal in the zoo has consumed 39 pounds of food in six days. If it continues to eat at the same rate, in how many more days will its total consumption be 91 pounds?

Solution:
Given,
In 6 days, the animal consumes = 39 pounds

So, in 1 day, the animal consumes = 39/6 pounds
= 6.5 pounds

The animal has already consumed 39 pounds.
Total consumption required = 91 pounds

So, the remaining food to be consumed = 91 - 39 = 52 pounds

Now,
6.5 pounds are consumed in 1 day
∴ 52 pounds are consumed in = 52/6.5 days
= 8 days

Therefore, it will take 8 more days for the total consumption to be 91 pounds.

Correct Answer: ঘ) 8
