Answer:
Productivity ratio is 21%
Explanation:
Productivity ratio measures the level of output achieved using a certain amount of resources. It is computed as the value of output to input.
Productivity ratio = output/input × 100
Input in cost :
Material cost
Material A = 500 × $1.2 =600
Material B = 360 × $2.50=900
Labour = 400 × $18=7200
Total cost = 600+900+7200= $8,700
Output- 1800 units
Productivity ratio in 2018 = 1800/8700 × 100
= 21%
