If A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’, then what will come in place of ‘?’ in the following equation? (9 A 9 C 55 D 5) B ? = 10 B 3 A 5
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 5
9 A 9 C 55 D 5) B ? = 10 B 3 A 5
A denotes ‘+’, B denotes ‘×’, C denotes ‘−’, and D denotes ‘÷’
(9 + 9 - 55 ÷ 5) × ? = 10 × 3 + 5
18 - 11 × ? = 35
7 × ? = 35
? = 5
Hence, 5 is the correct answer.
