Answer:
45
Step-by-step explanation:
We know that,
If we have the numbers of the form xyz.
This gives that, x is placed at the hundredth place, y is placed at the tens place and z is located at ones place.
Since, we need a number between 20 and 50 having both tens and ones place.
We can take any number from 20 to 50.
For e.g. Let us take 45.
In 45, 4 is placed at the tens place and 5 is placed at the ones place.
Hence, 45 is the number between 20 to 50 having both tens and ones place.
