Question

3415 1267 2769 4219 1538 if 220 is added to each of the above number after interchanging the first with third digit as well as second digit with fourth digit with in the number now sum of digikts how many numbers of how many of them are multiplies of 2?

Answer 1

Given that,

The numbers are,

3415, 1267, 2769, 4219, 1538

If 220 is added to each of the above number.

3635, 1487, 2989, 4439, 1758

Now, interchanging the first with third digit as well as second digit with fourth digit with in the number now sum of digits

$3+5+3+6, 8+7+1+4, 8+9+2+9, 3+9+4+4, 5+8+1+7$

$17, 20, 28, 20, 21$

We need to calculate the how many number of multiple of 2

Using formula of multiple

A digit that is divided by another digit and no reminder is left after division.

So, For first number,

$\dfrac{17}{2}=8.5$

This is not a multiple of 2.

For second number,

$\dfrac{20}{2}=10$

This is a multiple of 2.

For Third number,

$\dfrac{28}{2}=14$

This is a multiple of 2.

For fourth number,

$\dfrac{20}{2}=10$

This is a multiple of 2.

For fifth number,

$\dfrac{21}{2}=10.5$

This is not a multiple of 2.

Hence, Three numbers 1267, 2769 and 4219 are multiple of 2.
