Question

If the weight of the bigger bag is three times the weight of the rice bag, what will be the reading of the weighing machine?

Weight of the rice bag = 5.25 kg

• A. 22.50 kg
• B. 21.50 kg
• C. 21.75 kg
• D. 21 kg

Answer 1

The correct option is D 21 kg

Weight of the rice bag
= 5.25 kg

Weight of the bigger bag
= 3 $\times$ 5.25 kg

There's 2 total decimal places in both numbers.

Do the multiplication by ignoring the decimal places.

Now, Place the decimal after 2 digit from right of this number.
Weight of the bigger bag
= 15.75 kg

Total weight
= 15.75 kg + 5.25 kg

= 21.00 kg
