A) 81:64

B) 64:55

C) 71:81

D) 71:55

E) 81:55

Answer:

Option E

Explanation:

= 4050 tonnesTotal production of Company A = (750 + 800 + 600 + 550 + 700 + 650) tonnes

Total sales of Company A = (300 + 550 + 450 + 400 + 500 + 550) tonnes

= 2750 tonnes

Required ratio = 4050 : 2750 = $\frac{4050}{2750}$

= $\frac{81}{55}$ = 81:55
