Question

Find all the numbers between $20$ and $40$ that are divisible by:

(a) $2$

Answer 1

Write all the numbers between $20$ and $40$ that are divisible by $2$.

We know that a number is divisible by $2$, if the digit at the ones place is an even digit, i.e., the digit at the ones place is $0,2,4,6$ or $8$.

So we can say, the numbers $22,24,26,28,30,32,34,36$ and $38$ are divisible by $2$.

Hence, all the numbers between $20$ and $40$ that are divisible by $2$ are $22,24,26,28,30,32,34,36$ and $38$.
