Question

If A, B, C, D, E, F, G, H, I, J represent 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 then (AB + CD) - GH = ?

• A. -44
• B. -43
• C. +44
• D. +43

Hint:

When working with such problems, substitute the values for the letters and perform the arithmetic carefully.

Answer 1

The Correct Option is B

The given problem assigns numerical values to letters: A = 0, B = 1, C = 2, D = 3, E = 4, F = 5, G = 6, H = 7, I = 8, J = 9. We need to compute the expression (AB + CD) - GH using these assignments.

First, substitute the numerical equivalents for the letters:

• AB = 01, which is 0 * 10 + 1 = 1
• CD = 23, which is 2 * 10 + 3 = 23
• GH = 67, which is 6 * 10 + 7 = 67

Calculate the expression step by step:

1. Find the sum of AB and CD:
   1 + 23 = 24
2. Subtract GH from this sum:
   24 - 67 = -43

Therefore, the result of the given expression (AB + CD) - GH is -43.
