$\huge\fbox{\color{red}{♡AnsweR♡}}$

Population of Montrose = 11000 people

Population of Islamabad = 5000 people

__________________________________

Number of people in Montrose whose age is under 40 : 5/8 of total population

$\frac{5}{8} \times 11000 \\ 5 \times 1375 \\ = 6875$

Number of people in Islamabad whose age is under 40 : 5/8 of total population

$\frac{5}{8} \times 5000 \\ 5 \times 625 \\ = 3125$

___________________________________

Number of people in Montrose who are over 40

= Total population - number of people who are under 40

= 11000 - 6875

= 4125 people

Number of population in Islamabad who are over 40

= Total population - number of people who are under 40

= 5000 - 3125

= 1875 people

________________________________

Therefore, 4125 people in Montrose and 1875 people in Islamabad are over 40. Overall, 6000 ( 4125 + 1875 ) people are over 40.
