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

Difficulty: Easy

Correct Answer: 137

Explanation:


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:

1) Replace: (50 ÷ 2) + (28 × 4).2) Inside brackets: 50 ÷ 2 = 25; 28 × 4 = 112.3) Sum: 25 + 112 = 137.


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
