Question

I am a number. I am more than 60 but less than 70. The digit in my tens is twice the digit in my ones place. What number am I?

Answer 1

hey your answer is :-

more than 60 but less than 70. = 61 - 69

So, the first letter is => 6.....(I)

Now,

The digit in my tens is twice the digit in my ones place =

let tens place be 2x and ones be x..

2x = 6 from (I)

x = 3

So the number is 63...

mark as brain list and thanks my 10 answer...

Answer 2

Step-by-step explanation:

let the no. on ones place be x

then the no. on tens place be 2x

no. = 2x×10+x

= 21x

now on putting x=1

21×1= 21 (less than 60)

on putting x= 2

21×2= 42. (less than 60)

on putting x= 3

21×3= 63 (greater than 60 but less than 70)

hence the no. is 63

.....666....
