If A denotes ‘+’, B denotes ‘×’, C denotes ‘-’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
27 B 5 C 38 A 16 D 4 A 42 C 8 B 4 =?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 111.
Given conditions: A denotes ‘+’, B denotes ‘×’, C denotes ‘-’, and D denotes ‘÷’
Given equation: 27 B 5 C 38 A 16 D 4 A 42 C 8 B 4 =?
After interchanging the expression becomes:
= 27 × 5 - 38 + 16 ÷ 4 + 42 - 8 × 4
= 27 × 5 - 38 + 4 + 42 - 8 × 4
= 135 - 38 + 4 + 42 - 32
= 135 - 38 + 46 - 32
= 181 - 38 - 32
= 181 - 70
= 111
Hence, 111 is the correct answer.
