(#M40007837) MCA question 5 digit number Keep an EYE

Can you find a five digit number that, if you place a 9 at the beginning to make a new number, is fours times larger than if you place the 9 at the end instead?

Solution

Let the number is 10000x+1000y+100z+10p+q
now according to the given condition
100000*9+10000x+1000y+100z+10p+q = 100000x+10000y+1000z+100p+10q+9
on solving we get 10000x+1000y+100z+10p+q = (900000-36)/39 = 23076
