Question

I am a multiple of 7 and a factor of 210. The product of my two digits is an odd
number. Which number am I​

Answer 1

Step-by-step explanation:

Factors of 210= 2*3*5*7

Factors which are multiple of 7 are 14,21,35 only two digit factors we consider

And it is also given that product of my two digits is odd

only 35 is the number whose digit's product (3 and 5) is ODD

But in case of 14 and 21 product of digits is EVEN

SO the Number is 35.

Answer 2

Answer:

The number is 35.

Step-by-step explanation:

Factors of 210 = 2 x 3 x 5 x 7

Factors that are multiples of 7 are 14, 21, 35

we are considering only two digits

and it's given that the product of my two digits is odd

hence only 35 is the number whose digits product ( 3 and 5 ) is ODD

but in the case of 14 and 21 product of digits is EVEN

⇒ So the number is 35.
