Question

Pls answer fast and ignore marks on the option

Answer 1

heya!!!

Let the digits be x and y

y = 2x ( given ) .... equation 1

Any two digit number can be written like this

10x + y

According to the question

10y + x = 18 + 10x + y

9y - 9x = 18

y - x = 2 ..... equation 2

Now, put value of equation 1 in equation 2

2x - x = 2

x = 2


and. y = 4


So, the ist no. is. 24


Have a great future ahead.
