Complete Question

  AB

 * C

____

  DE

+ FG

______

 HI

Here  AB * C  = DE  ( is one operation)

DE + FG  =  HI    ( another operation)

there is no linkage directly between AB & HI

A to I digit 1 to 9

17 * 4  = 68

68 + 25 = 93

 17

 * 4

____

  68

+ 25

______

   93

All digits used from 1 to 9

Here is how we reached to solution

All digits used from 1 to 9

ab* c  = de

de + fg = hi

1 to 9 digit

hi two digit

b , c can not be 1  or 5

as ab * 1 = ab => ab = de ( with same digits)

a1 * c will end with c   a5 * c  will end with 5 or 0

ab * 5 will end with 0 or 5   ( 0 not available , 5 will be repeated digit in c & i)

Let s check all possible

11 , 12 * 1 , 12 * 2 ,  12 * 3 = 36 , 12 *  4 = 48 , 12 * 5 ,12*6 = 72 , 12 * 9 = 108 ( not possible)

12 * 7 = 84  remaining digits 3 , 5 , 6  9   35 + 69 = 104  ( not satisfied)

12 * 8 = 96 ( remaining digits 3 , 4 , 5 , 7 ) not  satisfied

13 * 1 , 13 * 2 = 26 , 13 * 3 , 13 * 5 , 13 * 7 = 91 , 13 * 8 = 104  ( not possible)

13 * 4 = 52 remaining digits 6 , 7 , 8 . 9 not  satisfied

13 * 6 = 78  remaining digits 2 , 4 , 5 . 9  not  satisfied

14 * 1, 14 * 2 = 28 , 14 * 3 = 42 , 14 * 4 , 14 * 5 , 14 * 6 = 84 , ( not possible)

14 * 7  = 98  remaining digits 2 , 3 , 5 . 6  not  satisfied  

15 , 16 * 1 , 16 * 2 = 32 , 16 * 4 = 64 , 16 * 5 . 16*6 , 16 * 7 = 112 ( not possible)

16 * 3  = 48   remaining digits 2 , 5 , 7 , 9   not  satisfied

17 * 1 , 17*3 = 51 , 17 * 5 , 17 * 6 = 102 ( not possible)

17 * 2 = 34   remaining digits 5 , 6 ,  8 , 9 not  satisfied

17 * 4 = 68   remaining digits 2 , 3 ,  5 , 9  (68 + 25 = 93)
