Study the following and the table and answer the questions given below. (Data of different states regarding population of states in the year 2018)
Total population of the given States = 3276000
Q3. If in the year 2018, population of F is increased by 10% and population of B is increased by 12% as compared to the previous year, then ______ is the ratio of population of F and B in 2017.
42 : 55  
62 : 55  
42 : 11  
44 : 5 
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
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

24%  
17.5%  
28.5%  
29.5% 
Question 12 Explanation:
Let population=X
Males of F in 2018 = (⅗)*15*(X/100) = 9X/100
Males of B in 2018 = (¾)*20*(X/100) = 15X/100
Males of D in 2018 = (⅜)*12*(X/100)=4.5X/100
Total=(28.5*X)/100
X=28.5%
Males of F in 2018 = (⅗)*15*(X/100) = 9X/100
Males of B in 2018 = (¾)*20*(X/100) = 15X/100
Males of D in 2018 = (⅜)*12*(X/100)=4.5X/100
