• A. a. 2 kg 965 g; b. 34.5 kg
• B. a. 2 kg 935 g; b. 37.6 kg
• C. a. 3 kg 500 g; b. 35 kg
• D. a. 3 kg 100 g; b. 36 kg

Answer 1

The correct option is B a. 2 kg 935 g; b. 37.6 kg

a. We have to perform subtraction.

Let’s convert the unit into g.
Since 1 kg = 1000 g,

2 kg 355 g = 2000 + 355 = 2355 g
5 kg 290 g = 5000 + 290 = 5290 g

Now, we subtract

5290 – 2355 = 2935 g

Then, 2935/1000 = 2.935 kg
Hence, it is 2 kg 935 g.

b. Geeta weighs 62.5 kg. Her daughter weighs 24.9 kg less than her.

So, Geeta daughter’s weight = 62.5 – 24.9 = 37.6 kg
