find the question where 95 - 59 is divided by 4​

Answer 1

Answer:

$let \: two \: number \\ ab = 10a + b \\ ba = 10b + a \\ then \\ ab - ba = (10a + b) -( 10b + a) \\ = 10a - a + b - 10b \\ = 9(a - b) \\ where \\ a = 9 \\ b = 5 \\ so \\ 95 - 59 = 9(9 - 5) = 9 \times 4 \\ question \: asked \: if \: it \: is \: divisible \\ by \: 4 \\ yes \\ \frac{9 \times 4}{4} = 9 \: \: \: \: (divisible)$
