Custom symbols — If T = ×, U = −, X = ÷, and W = +, evaluate (50 X 2) W (28 T 4)

Introduction / Context:Symbol mapping questions require careful replacement followed by normal arithmetic precedence. Brackets must be evaluated first.

Given Data / Assumptions:

• T → multiply (×)
• U → minus (−)
• X → divide (÷)
• W → plus (+)
• Expression: (50 X 2) W (28 T 4)

Concept / Approach:Replace symbols, compute bracketed parts, then add.

Step-by-Step Solution:

Verification / Alternative check:Compute again independently: both parts 25 and 112 are straightforward, summing to 137.

Why Other Options Are Wrong:

• Values like 142/158/163 stem from swapping one of the mappings or adding before multiplying.

Common Pitfalls:

• Forgetting that X means division here.

Final Answer:137
