Efficiency implies i. Maximum output from given input ii. Same output from same input iii. Given output from lesser inputs. iv. It is not possible to get any more output from the same level of inputs Choose correct option:

i,ii i, iii, iv i, ii, iii i, ii, iv

i, iii, iv

Efficiency is relation between inputs and outputs and can mean any of the following i. Maximum output from given input ii. Given output from lesser inputs iii. It is not possible to get any more output from the same level of inputs, that is, one is producing maximum output from given inputs
