Question

A lorry can carry 72 boxes of biscuits. The weight of each box is 15 kg. A mini van can carry 28 boxes of biscuits each of the same weight. Find the total weight that can be carried by both the vehicles using the suitable property.​

Answer 1

Answer The answer is 1500 kg.

Step by step explanation

1. step 1 - According to suitable property 72 boxes * 15 kg is written as 72 *( 10 + 5).
2. (72 *10) + (72 * 5)
3. 360 + 720 = 1080 kg
4. step 2 - 28 boxes * 15 kg is written as 28 * ( 10 + 5).
5. (28* 10) + ( 28* 5)
6. 140 + 280 = 420 kg

Now in the 3 and 6 sentence I have put 0 's in the after 72 and 28 and thats because in the normal process of multiplication we put 0's from the next step . And in this case if we do not put the 0 .The answer will be wrong.

1. Then add 1080 kg + 420 kg = 1500kg

Hope this helps.
