Question

Find the 3 digit code using the clues given below :

7 2 6 - One number is correct and well placed
3 2 9 - One number is correct but wrong placed
6 5 3 - One number is correct and well placed
9 4 8 - One number is correct but wrong placed

Answer 1

-6624
it is not common practice in mathematics to place numbers after braces in the manner 2 and 7 have been placed. In case they refer to multiplication of solutions within braces, the answer comes to -6624. In case 2 and 7 are exponents the answer would be different.

Answer 2

2[2{3-6(4*5)2}7+6]
=2[2{-12*20}7+6]
=2[2{3-240}7+6]
=2[14{-237}+6]
=2[-3318+6]
=2[-3312]
=-6624
