A 2 digit is such that the product of its digits is 20.if 9 is added to the number the digits interchange their places find the number. with all the steps

Let the digits of the 2nos. be x and y respectively....x is the digit in the tens place and y in the units place....from the first statement we get : x*y=20...............(i) and from the second statement we find: 10*x +y =20 ......................(ii) on solving (i) and (ii) .... u will get x=4 and y=5 so the answer is 45

dude solve it properly ,its a standard question ,ull get it

ya i did that.....and my solution is correct...if u thnk its wrong give me a check ...!!

let x= once digit and y is tenth digit. Then , number is 10y+x So, if the digits interchange their places, then the number is 10x+y now, xy=20 ....(i) 10y+x+9=10x+y or 9x-9y=9 or x-y=1 ..(ii) From (i) and (ii) , we get x(x-1)=20=4X5 x=4 or 5 , but as x-y=1 , then x=5 and y=4 The number is 45.

thats what i did!! instead of fully solving it....i gave the equations!!
