If A denotes +, B denotes -, and C denotes ×, then what will be the value of the following equation?
20 C 5 A 3 C 2 B 16
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 90.
Given equation: 20 C 5 A 3 C 2 B 16
Given equations: A denotes +, B denotes -, and C denotes ×
After interchanging the expression becomes:
= 20 × 5 + 3 × 2 - 16
= 100 + 3 × 2 - 16
= 100 + 6 - 16
= 106 - 16
= 90
Hence, 90 is the correct answer.
