First read this theory.
John(25yrs male) & mary(22yrs female) after their marriage they decided to leave their parents village & go in search for a beutiful land which they hope it will be of milk and honey, they found a nice island which they later dwell.

Then.
Within 35yrs they gave birth to 6 children, 3boys 3girls,

namely
Moses (34 m),
sly (32 m),
tony (30 m) and
joy ( 28 f)
anita (26 f)
rose (24 f).

Then the father at 55 told them to get married to themself and start having children.
So Moses got married to joy,
sly married anita, & tony married rose.

And at another 35ys the children give birth to 6 grand children each for John.

Then, And at another 15yr those grand children also give birth to 6 great grand children each for John.

Then John dead at 100ys and hes wife mary 97, leaving behind their 6 children,
18 grand children and 51 great grand children.

Now what is the total population and at what % its increasing in a space of a centuery(100ys)?
We are told that world population is 7 billion. What will happen in another 100yrs?

What is nigeria government going to do in vision 2050? What will happen to 3000 maga wax power capacity?

Can someone do the carculation
