Q1. If the ratio of population of females and children in colony A in year 2016 is 3 : 7, and female in colony A in year 2017 is increased by 20% from that of year 2016. Then find the total number of males and children in colony A in year 2017 so that overall population in year 2017 is same as in year 2016 ?
1752
1852
2752
3200
1527
Solution:

96
86
76

67
Solution:

Q3. If total population of colony B and colony C together in year 2016 is 25% more than the total population of colony A in year 2016 and ratio of total population of colony B and colony C in year 2016 is 2 : 3. Then find the ratio of males in colony B to children in colony C in year 2016 ?
9 : 8
8 : 9

cannot be determined
None of these
Solution:
Let males in colony D = 2x
Females in colony A = 5x
Let population of children in colony A in 2016 = a%
∴ No. of children in colony A in 2017 =(6a/5) %
From here we cannot find the required answer
