SOLUTION

TO CHECK

True / False below statement

If xy = 20 , then x and y varies directly

EVALUATION

Here it is given that

\displaystyle \sf{ xy = 20}

\displaystyle \sf{ \implies y =  \frac{20}{x} }

\displaystyle \sf{ \implies y  \propto \frac{1}{x} }

Thus we observe that as x increases y will decrease

Also as y increases x will decrease

Hence x and y varies inversely

FINAL ANSWER

Hence the statement is FALSE
