Question

If eachweighs 1 ounce, how many more such weights should be added to the right side of the balance so there are equal weights on both sides of the machine?

• A. 7
• B. 5
• C. 6
• D. 4

Answer 1

The correct option is B 5

Weight on left side of the machine = 1 pound = 16 ounces
Number of weights kept on the right side = 11
So, weight on right side of the machine = 11 ounces
Weight to be added on right side of the machine to make both sides equal = 16 - 11 = 5 ounces
Hence, 5 weights of 1 ounce each should be added to the right side of the weighing machine.
