for 150% you can say 150/100% so the number 20 is actually you 100% and you want to know how much is 150% of it so you can say : 150/100 = ?/20 now you can say ? = (20×150)/100 = 30 so 150% of 20 is 30 :)))))
i hope this be helpful

"150%" means "1.5"

"of" means "times"

So  "150% of 20" means "1.5 times 20" .

           1.5 x 20  =  30
