Question

3. How will you weigh
(a) 3 kg onions by using a 5 kg and a 2 kg weights?
(b) 4 kg rice by using a 5 kg and a 1 kg weight?​

Answer 1

Answer:

Step-by-step explanation:

(a) Place the onions and 2 kg weight on 1 side and the 5 kg weight on the other side.

When 3 kg onions will get loaded, total weight on that side = 3 + 2 = 5kg

Weight on the  other side = 5kg, so the weighing scale will get balanced.

(b) Similarly, Place the 1 kg weight and $kg rice on one side and the 5 kg weight on the other side.

Answer 2

a. Put the 5kg weight on one side and 2kg weight + the onions on other side of the weight scale

When the weight becomes equal, you have 3 kg of onions.

b.Put the 5kg weight on one side and 1kg weight + rice on the other side of the weight scale.

When the weight becomes equal, you have 4kg of rice.
