 A 42 : 55 B 62 : 55 C 42 : 11 D 44 : 5
Data-Interpretation       Data-Interpretation-Ratio       NIC-NIELIT Scientist-B 2020
Question 11 Explanation:
F 2018 = (15/100)*3276000
B 2018 = (20/100)*3276000
F increased by 10% in 2018.
B increases by 12% in 2018.
So, F 2017→ 1.1 times= 15*32760
B 2017→ 1.12 times = 20*32760
F 2017 : B2017 = [(15*3276)*10]/11 : [(20*32760)*100]/112
= 42:55
