If a person is born every 5 seconds and a person dies every 12 seconds, then how many seconds does it take for the population to

harina [27]

Solution:

As per the problem

A person is born every 5 seconds and a person dies every 12 seconds.

Here the LCD of 5 and 12 is 60.

The number of person born in 60 seconds $=\frac{60}{5}=12\\$

The Number of person died in 12 seconds $=\frac{60}{12}=5$

Hence Population increase in 60 seconds is $=12-5=7\\$

Hence time required to increase the population by one $=\frac{60}{7} \ \ seconds\\$

Step-by-step explanation:

$using \: pythagoras \: theorem \\ let \: the \: unknown \: side = x \\ 25 {}^{2} = x {}^{2} + 20 {}^{2} \\ 625 = x {}^{2} + 400 \\ x {}^{2} = 625 - 400 \\ x {}^{2} { = 225} \\ x = \sqrt{225} \\ x = 15 \\ lenght \: of \: the \: third \: side = 15$
