Correct Answer - Option 4 : 157.5 kg
Given:
Number of parcels = 15
Weight of each parcel = \(10 \dfrac{1}{2}\) kg
Formula Used:
Total weight = Number of parcels × Weight of 1 parcel
Calculations:
Number of parcels = 15
Weight of each parcel = 21/2 kg
Now, Total weight = Number of parcels × Weight of 1 parcel
⇒ Total weight = 15 × 21/2 kg
⇒ Total weight = 157.5 kg
∴ The total weight of the parcels is 157.5 kg.
