Step-by-step explanation:
Question no1
Let us take the population one year ago be x.
Then the population after one year = 115x/100.
But it is given 20700.
So Atq. ,115x/100= 20700
Plz mark brainliest
or x.= 20700×100/115
Therefore x =18000.
Therefore the population one year was 18000.
Question no2
Given, total no.of trees 64
No.of apple trees = 25/100×64i.e 16
No.of lemon trees = 62.5/100×64i.e40
therefore no.of banana trees = 64-56/100×64i.e 8
