Question

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

Answer 1

Hey mate here's the answer:-

Given, a > c  To show : abc – cba = 99(a – c)  Proof: abc = 100a + 10b + c ……….(i) (By using property 3)  cba = 100c + 10b + a ………..(ii)  (By using property 3)  Subtracting, equation (ii) from (i), we get  abc – cba = 100a + c – 100c – a abc –  cba = 99a – 99c abc – cba = 99(a – c) Hence proved.

Hope it helps.......
