I would say c is the correct answer as if there is a low birth rate, when the population ages you are going to have lots of people retiring and not as many people working and paying taxes so pressures on pensions and social security programs will rise. Hope this helps :)
Answer: 340m
Explanation:
Given that:
Streets are constructed from 10 m pieces;
A lamppost is placed at both ends and at every 10 m along its length ;
A lamppost is also placed at every notice board along its length :
Given that:
Einstein Street has 42 lamppost and 7 notice boards :
So,
7 lamppost for 7 notice boards :
Lamppost left = 42 - 7 = 35 lamppost
2 lamppost placed at both ends :
Lamppost left = 35 - 2 = 33 lamppost
Hence, the remaining is placed at 10 m along its length:
Hence, length of Einstein street :
33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m
Distance between 33rd lamppost and the ending lamppost = 10m
Hence, total length = (330 + 10) = 340 m
