Rishav Verma  (8 years ago)

A 5 C 5 D=8
-1 B 8 7 C=3
----------- B=7
6 7 4 D A=8

7*A+5*B+6*C*D=7*8+5*7+6*3*8=56+35+144
=235

Is this solution Helpfull? Yes (5) | No

1) 5-7 , so we borrow 10 from C
Therefore, 15-7 = 8 = D and decrease value of C by 1
2) x - 8 = 4 -> x=12 , ie, we borrow 10 from 5 (5-1)
Therefore, C-1=2 -> C=3
3) 4-B=7, so we borrow 10 from A (A-1)
Therefore, 14-B=7 -> B=7
4) (A-1) -1 = 6 -> A=8

Therefore, A=8,B=7,C=3,D=8

Therefore, ans is 235

Is this solution Helpfull? Yes (2) | No
