Question

which is the smallest integer that is 4 times the sum of its digits....tell the ans by showing the process too

Answer 1

2 is the smallest integers

Answer 2

let the required integer be 10a+b.
a/q
10a+b=4 (a+b)
10a+b=4a+4b
10a-4a=4b-b
6a=3b
6a-3b=0
3 (2a-b)=0
-3 (2a+b)=0
2a+b=0/-3
a+b=0/-3*2
10*a+b=10*0/-6
= 5/-3
= -5/3
hope this is correct.....i don't know tge right answer :(
