Correct Answer:
Option C - According to the question,
Sum of total production = type A (2018) + type E (2019)
= 56 + 64 = 120
Sum of total production of type C and type D in 2016
= 43+47 = 90
Hence required ratio = 120 : 90
= 4 : 3
C. According to the question,
Sum of total production = type A (2018) + type E (2019)
= 56 + 64 = 120
Sum of total production of type C and type D in 2016
= 43+47 = 90
Hence required ratio = 120 : 90
= 4 : 3
