Question

Rehan bought 5 kg of wheat and 2500 grams of rice. How many kilograms worth wheat and rice does he have tp carry home?
  1. 7.0 kg
  2. 7.5 kg
  3. 3.0 kg
  4. 5.25 kg


Solution

The correct option is B 7.5 kg
Since we want the final answer in kilograms, let us convert 2500 grams of rice into kilograms.
We  have 1 kg = 1000 g.
1 g =11000 kg
2500 g = 2500×11000 kg=2.5 kg

Now, the total weight of rice and wheat is given by 5 kg + 2500 g = 5 kg + 2.5 kg = 7.5 kg.
