| 2) 12 boxes weight 21 kg. How much will 7 such boxes weight Answer: 12 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (7 x = = 12 |
| 3) 13 boxes weight 18 kg. How much will 6 such boxes weight Answer: 8 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (6 x = = 8 |
| 4) 10 boxes weight 24 kg. How much will 8 such boxes weight Answer: 19 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (8 x = = 19 |
| 5) 15 boxes weight 18 kg. How much will 6 such boxes weight Answer: 7 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (6 x = = 7 |
| 6) 15 boxes weight 11 kg. How much will 6 such boxes weight Answer: 4 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (6 x = = 4 |
| 7) 15 boxes weight 31 kg. How much will 7 such boxes weight Answer: 14 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (7 x = = 14 |
| 8) 12 boxes weight 20 kg. How much will 7 such boxes weight Answer: 12 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (7 x = = 12 |
| 9) 12 boxes weight 37 kg. How much will 4 such boxes weight Answer: 12 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (4 x = = 12 |
| 10) 15 boxes weight 13 kg. How much will 6 such boxes weight Answer: 5 kg SOLUTION 1 : Given :
As the No of boxes decreases, the Weight of the boxes also decreases. It is in direct variation. So, = Constant = a = (6 x = = 5 |
