1.	Both x and y are in direct proportion, then 1/x and 1/y are:(a) in indirect proportion. (b) in inverse proportion. (c) neither in direct nor in inverse proportion. (d) sometimes in direct and sometimes in inverse proportion.
Answer» (b) If both x arid y are in directly proportion, then 1/x and 1/y are in inverse proportion. Hence, option (b) is correct. Note: Two quantities x and y are said to be in inverse proportion, if an increase in x cause a proportional decrease in y and vice-versa.
