What will come in place of the question mark (?) in the following equation if ‘a’ means ‘÷’, ‘b’ means ‘+’, ‘c’ means ‘−’ and ‘d’ means ‘×’?
11 b 15 c 8 a 4 d 5 = ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 16.
Given: 11 b 15 c 8 a 4 d 5 = ?
Replacing the sign in equation,
11 + 15 - 8 ÷ 4 × 5 = ?
= 11 + 15 - 2 × 5
= 11 + 15 - 10
= 26 - 10
= 16
