Question

There are 90 kg of mangoes in a box. If 8 kg 700 g of these are rotten, then what is the weight of the remaining mangoes?
1. 82 kg 300 g
2. 81 kg 300 g
3. 79 kg 900 g
4. 83 kg 200 g

Answer 1

Correct Answer - Option 2 : 81 kg 300 g

Given:

Total 90 kg mangoes in the box

And, 8 kg 700 g mangoes are rotten

Concept used:

1 kg = 1000 gram

Calculations:

The total weight of mangoes in the box is 90 kg

The weight of rotten mangoes is 8 kg 700 g

We can write it as 8.700 kg

According to the question, we have

Remaining mangoes = Total weight of mangoes - Rotten mangoes

⇒ 90 - 8.700

⇒ 81.300 kg

We can write it as 81 kg 300 g

∴ The weight of the remaining mangoes is 81 kg 300 g
