Answer 2

Step-by-step explanation:

If 2/5 orange box weighs 4kg 200gm, then the weight of the full box can be found by unitary method. In this we would first find 1/5 of the box and the we would multiply the result with 5. So, lets first convert the weight into grams. So let the 1/5 of the box be x. So,

2x = 4200

or x = 4200 ÷ 2

or x = 2100.

So, the weight of orange box is

2100 × 5 = 10500 gm or 10 kg 500gm
