Question
Smith used a pan balance and metric weights to measure the total mass of 3 bricks. What is the mass of the 3 bricks?
- 3kg
- 6kg
- 9kg
- 6g
Hint:
In the question, it is given that Smith used a pan balance and metric weights to measure the total mass of 3 bricks. In the picture, 3 metric weights (1 kg each) are shown. The principle of pan balance is to create an opposite force compared to the unknown mass(in this case, 3 bricks). The 2 pans are balanced against each other. Hence the weight in both the pans must be equal. Thus, the mass in both the pans are equal. So, in this question, we just need to equate the mass of the 3 metric weights and the 3 bricks.
The correct answer is: 6kg
Step by step solution:
Given, 3 metric weights each of 1 kg are given and it balances out the 3 bricks.
Hence, total mass of 3 bricks = 1 kg + 1 kg + 1 kg
= 3 kg
Thus, option (a) is the correct option.

The total capacity represented in the picture is
Alternatively, the question can be solved as-
GIVEN-
Capacity of jug 1 = J1 = 250 ml = (250/1,000) l = 0.25 l ....................... (1l = 1,000 ml)
Capacity of jug 2 = J2 = 500 ml = (500/1,000) l = 0.5 l ....................... (1l = 1,000 ml)
Capacity of jug 3 = J3 = 500 ml = (500/1,000) l = 0.5 l ....................... (1l = 1,000 ml)
Capacity of jug 4 = J4 = 1 l
Capacity of jug 5 = J5 = 1 l
TO FIND-
Total capacity of all the jugs in the given picture.
SOLUTION-
Total of jugs in the given picture = J1 + J2 + J3 + J4 + J5
∴ Total of jugs in the given picture = 0.25l + 0.5 l + 0.5 l + 1l + 1l
∴ Total of jugs in the given picture = 3.25 l
Final Answer remains the same.
