उत्तर
The weight should be removed to make the weight equals to 700 kg
= 835 – 700 = 135 kg.
The weight of 3 sacks of rice = 105 kg
The weight of three tables = 30 kg
Total weight of these things = 105 + 30 = 135 kg
So, if they remove 3 sacks of rice and three tables, then the weight will become 700 kg.
