Answer 1

Answer:

25

Step-by-step explanation:

you are 25.

digits of 25 = 2 and 5

2+5 = 7

Answer 2

Given: The required number is a factor of 100 and its digits add upto 7

To find: The required number

Solution: Since this unknown number is a factor of 100, first we find all the factors of 100.

As such, the factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50 and 100.

Now we need to figure out the sum of the digits of which of these factors is equal to 7.

We can clearly omit out the single digit numbers from this consideration.

From the rest of the numbers, we can see that the digits of 25 sum upto

7 (= 2 +  5).

Hence, the required number which is a factor of 100 and whose digits add upto 7 is 25.

Answer: 25
