Question

Father gave them some idea of the weight of each thing.

Thing loaded	Weight
A sack of wheat	100 kg
A sack of rice	35 kg
Water tank	50 kg
Almirah	70 kg
A table	10 kg
A chair	5 kg
A mattress	20 kg
Bamboo ladder	10 kg
Pots and pans	10 kg

• Find out the total weight they had loaded on the cart.
Now they decided to remove a few things from the cart.
• Which things should be removed so that the weight of the load is not more than 700 kgs?

Answer 1

• Weight of a water tank = 50 kg

Weight of 1 sack of wheat = 100 kg
Weight of 5 sacks of wheat = 5 × 100 kg
= 500 kg
Weight of 1 table = 10 kg
Weight of 3 tables = 3 × 10 kg
= 30 kg
Weight of an almirah = 70 kg
Weight of 1 chair = 5 kg
Weight of 4 chairs = 4 × 5 kg
= 20 kg
Weight of 1 mattress = 20 kg
Weight of 2 mattresses = 2 × 20 kg
= 40 kg
Weight of 1 sack of rice = 35 kg
Weight of 3 sacks of rice = 3 × 35 kg
=105 kg
Weight of a bamboo ladder =10 kg
Weight of pots and pans = 10 kg
Total weight loaded on the cart = 50 kg + 500 kg + 10 kg + 30 kg + 70 kg + 20 kg + 40 kg + 105 kg + 10 kg + 10 kg
= 845 kg

• Weight of a water tank = 50 kg

Weight of an almirah = 70 kg
Weight of 3 tables = 30 kg
Total weight = 50 + 70 + 30 kg
= 150 kg
3 tables, an almirah and a water tank are removed.
∴ Total weight loaded on the cart = 845 kg − 150 kg
= 695 kg
Working:
$\begin{array}{cccc}& 8& 4& 5\\ -& 1& 5& 0\\ & 6& 9& 5\\ & & & \end{array}$

Thus, the tables, an almirah and a water tank should be removed so that weight of the load is not more than 700 kg.
