Correct Answer - Option 1 : 47000 gram
Given:
Weight of four boxes are respectively 10 kg 900 gram, 15 kg 300 gram, 12 kg 500 gram, and 8 kg 300 gram.
Formula Used:
1 kg = 1000 gram
Calculation:
As, the weight of the boxes are 10 kg 900 gram, 15 kg 300 gram, 12 kg 500 gram and 8 kg 300 gram
So, sum of the weight of boxes = (10.900)kg + (15.300)kg + (12.500)kg + (8.300)kg
= 47 kg
And, as 1 kg = 100 gram
So, 47 kg = 47 × 1000 = 47000 gram
∴ Total of 47000 grams is kept in the 4 boxes.
