Question

if a>c show that abc - cba = 99(a-c)

Answer 1

"If a>c

Let’s take 99(a-c) = 6mn

Instead of 99(a-c) substitute 6mn in the equation abc - cba = 99(a-c)

100a+10b+c - (100c+10b+a) = 6mn

Multiples of 99 are 99,198,297,396,495,594,693

So 6mn = 693

Were m+n = 12.

Therefore, abc - cba = 99(a-c)

Hence proved. If a>c show that abc - cba = 99(a-c)
