Download Solution PDFGiven:
Average weight of 97 notebooks = 9.7 kg
New average weight after adding 1 notebook = 9.8 kg
Formula Used:
Weight of new notebook = Total weight after adding 1 notebook - Total weight before adding
Calculation:
⇒ Total weight of 97 notebooks = 97 × 9.7
⇒ Total weight of 97 notebooks = 940.9 kg
⇒ Total weight of 98 notebooks = 98 × 9.8
⇒ Total weight of 98 notebooks = 960.4 kg
⇒ Weight of new notebook = 960.4 - 940.9
⇒ Weight of new notebook = 19.5 kg
∴ The weight of the new notebook is 19.5 kg.
