Step-by-step explanation:
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)
