In which of these relations will S double if T is doubled?
A) S = 10T
B) T = 1/S
C) T = S*S
D) S = 1/T

Question

Quizplus · Accepted Answer

In option A, if T is doubled then S will also be doubled, as S is directly proportional to T with a factor of 10. In options B, C, and D, doubling T will not result in a doubling of S. Option B shows an inverse relation between S and T, so doubling T will result in halving S. Option C shows that S is equal to the square of T, so doubling T will result in quadrupling of S. Option D shows an inverse relation between S and T, so doubling T will result in halving S.
