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 3 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

Correct Answer: A

**Question 3 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
