Reasoning (Question:1091639.0)

Iss question mai $ की जगह क्या होगा

Question:
If 11 - 2 $ 10 = 70 and 1 - 6 $ 4 = 16, then in the expression 17 - A $ 6 = 69, what is the value of 'A'?
Options:

C) 6
D) 5

The logic followed here is,

For 17 - A $ 6 = 69

'-' = '+' , '$' = 'x' and (after $ Symbol number brack equal part)

Following mathematical operation is done:

Step I: (17+A) x 3+3 = 69

Step II: (17 + A) x  3 = 69 - 3

Step III: 17 + A = 66/3

Hence, A = 22-17 = 5

Dear student
Here;
11 - 2 $ 10 = 70
(11+2) x 5 = 13 x 5 = 65 +5=70;
1 - 6 $ 4 = 16
(1+6) x 4 = 7 x 2 = 14 +2=16;
