(11) A company uses: 290 input units of raw material to produce 180 product units, if the labour cost is 90S.R, materials cost 105S.R and the overhead is 65S.R. then the productivity is : (a) 1.61% (b) 69.23% (c) 62.06% (d) None of the above (e) No enough data to calculate For question No 10: the productivity growth for this period is: (a) 1.61% (b) 69.23% (c) 62.06% (d) No enough data to calculate (e) None of the above 3 For question No 10: the multifactor productivity measure for this period is: (a) 1.61% (b) 69.23% (c) 62.06% (d) None of the above (e) Now enough data to calculate
