Question

If two quantities are in inverse proportion, then:

• A. When one quantity increases, the other will decrease by a fixed constant.
• B. Since an increase in one quantity causes a decrease in the other quantity, the sum of the quantities will be zero.
• C. If one quantity decreases, the other will increase at the same rate.
• D. Since an increase in one quantity causes a decrease in the other quantity, the product of the quantities will be always equal.

Answer 1

Answer: (C), (D)

The correct options are
C If one quantity decreases, the other will increase at the same rate.
D Since an increase in one quantity causes a decrease in the other quantity, the product of the quantities will be always equal.

If two quantities are in inverse proportion, then the increase in one quantity will cause a decrease in the other quantity at the same rate. We cannot determine the sum or product of the quantities, nor the rate of decrease, unless we know the numerical values of the quantities.
