Question

What is the difference between the no. of letters of the English alphabet which, when written in upper-case, remain unchanged in their mirror image and water image respectively?

• A. 5
• B. 3
• C. 2
• D. 4

Answer 1

The correct option is C 2

Letters which remain unchanged in their mirror image: A, H, I, M, O, T, U, V, W, X, Y = 11
Letters which remain unchanged in their water image: B, C, D, E, H, I, K, O, X = 9

So, the difference = (11 – 9) = 2.
