If A denotes ‘+’, B denotes ‘×’, C denotes ‘-’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation?
124 D 4 C 86 D 2 A 61 A 17 B 3 = ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 100.
Given conditions: A denotes ‘+’, B denotes ‘×’, C denotes ‘-’, and D denotes ‘÷’
Given equation: 124 D 4 C 86 D 2 A 61 A 17 B 3 = ?
After interchanging the expression becomes:
= (124 ÷ 4) - (86 ÷ 2) + 61 + 17 × 3
= 31 - 43 + 61 + (17 × 3)
= 31 - 43 + 61 + 51
= 143 - 43
= 100
Hence, 100 is the correct answer.
