Answer» The number would (a×b),(a×c),{(a×b)+(a×c)-c} reverse. using this technique,to get answerSo for 1st one: 3+5+6=151872axb = 3×5 = 15; axc = 3×6 = 18{(a×b)+(a×c)-c} = ((3×5)+(3×6)-6} = 27— Reverse of 27 is 72So 9+4+7=.................axb = 9×4 = 36axc = 9×7 = 63{(a×b)+(a×c)-c} = ((9×4)+(9×7)-7} = (36+63-7)=92 —>Reverse of 92 is 29.Hence 9+4+7 = 36632
