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
