If ‘U’ stands for ‘÷’, ‘D’ stands for ‘×’, ‘B’ stands for ‘+’, and ‘T’ stands for ‘–’, what will come in place of the question mark (?) in the following equation?
13 T 26 U 13 D 24 B 7 =?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. -28.
Given the equation: 13 T 26 U 13 D 24 B 7 = ?
Given conditions: ‘U’ stands for ‘÷’, ‘D’ stands for ‘×’, ‘B’ stands for ‘+’, and ‘T’ stands for ‘–’
After interchanging the expression becomes:
= 13 – 26 ÷ 13 × 24 + 7
= 13 – 2 × 24 + 7
= 13 – 48 + 7
= 20 - 48
= -28 = -28
Hence, -28 is the correct answer.
