Question

दो अंको की एक संख्या व अंको के स्थान बदल देने से प्राप्त संख्या का अंतर 9 आता हैं ।संख्या मे अंको मे अंतर ज्ञात कीजिए । ​

Answer 1

Answer:

Difference is 1

Step-by-step explanation:

Let the number consists of two digits x and y

where y is in unitary place

Then the number is 10x+y

If we change the positions of the digits the new number becomes 10y + x

Given difference is 9

So, 10x+y - (10y+x) = 9

Or, 9x-9y = 9

Or, (x-y) = 1

Answer 2

man liya ki ikai ka ank =x

man liya ki ikai ka ank =x Dahayi la ank =y

man liya ki ikai ka ank =x Dahayi la ank =yIsliye Sankhya =10y+x

man liya ki ikai ka ank =x Dahayi la ank =yIsliye Sankhya =10y+xAsthan Badlney pr prapt sankhya=10x +y

man liya ki ikai ka ank =x Dahayi la ank =yIsliye Sankhya =10y+xAsthan Badlney pr prapt sankhya=10x +y Prasn Se :-

man liya ki ikai ka ank =x Dahayi la ank =yIsliye Sankhya =10y+xAsthan Badlney pr prapt sankhya=10x +y Prasn Se :-10y+x -(10x+y)=9

10y+x-10x-y=9

9y-9x=9

Y-x=1
