Question

A considerable amount of water will be reduced while honeybees extract is processed
from flower nectar. What is the amount of flower nectar should be processed to yield a
3 kg of honey, if nectar contains 80% water, and the honey obtained from this nectar
contains 25% non-water part?​

Answer 1

Answer:

option A

Step-by-step explanation:

Solution

Given

In this question, we are given that

• Flower nectar is processed to extract honeybees

• Nectar contains 70% water, and the honey obtained from this nectar contains 17% water

To find

We need to determine

• The amount of flower nectar must be processed to yield 1 kg of pure honey

Approach and Working out

Flower-nectar contains 30% of non-water part.

In honey this non-water part constitutes (100 − 17) % or 83%

• Therefore (0.3) x Amount of flower-nectar = (0.83) x Amount of honey = 0.83 × 1 kg = 0.83 kg

Hence, the amount of flower-nectar needed = (0.83/0.3) = 2.77 kg

Thus, option A is the correct answer.
