• B. 2 sacks of 750 g each.
• C. 100 packets of 10 g each.
• D. 15 balls of 50 g each.

Answer 1

Answer: (A), (C)

100 packets of 10 g each.

We know that 1000 g = 1 kg.

Total weight of 4 boxes (250 g each)
$=4\times 250\text{g}=1000\text{g}=1\text{kg}$
4 boxes of 250 g each $\text{✓}$

Total weight of 2 sacks (750 g each)
$=2\times 750\text{g}=1500\text{g}=1\text{kg}500\text{g}(>1\text{kg})$
2 sacks of 750 g each $\text{✘}$

Total weight of 100 packets (10 g each)
$=100\times 10\text{g}=1000\text{g}=1\text{kg}$
100 packets of 10 g each $\text{✓}$

Total weight of 15 balls (50 g each)
$15\times 50\text{g}=750\text{g}(<1\text{kg})$
​​​​​​​15 balls of 50 g each $\text{✘}$
