Question

2,3,9=161
4,2,5=375
1,4,6=54
7,8,1=?

Answer 1

Answer:

619

Explanation:

2x100-39=161

4x100-25=375

1x100-46=54

7x100-81=619

Answer 2

Answer:

7, 8 , 1 = 66

Explanation:

Given

2, 3, 9=161----------A;

4, 2, 5=375 1-----------------B;

4, 6=54--------------C;

We need to find 7, 8, 1=? ---------D

Solve A, by multiplying 100 with 1st value and subtract 2nd and 3rd value, in order to equate LHS=RHS, apply this for all the 3 equation and verify.

2x100-39=161

We come to know that the LHS=RHS for A.

4x100-25=375

We come to know that the LHS=RHS for B.

1x100-46=54

We come to know that the LHS=RHS for C.

7x100-81=61

We come to know that the LHS=RHS for C.

So, from this we come to know the RHS value of D which is 61.
