1. 

If 'x' means subtraction; '-' means division, '◻' means addition and '%' means multiplication, then find the value of 13 ◻ 3 x 6 % 8 - 4 ◻ 14 = ?
A. 18
B. 14
C. 12
D. 8

Answer: Option A

Explanation:

Given, ? = 13 ◻ 3 x 6 % 8 - 4 ◻ 14

Now, changing the symbols into the sign as per question,

      ? = 13 + 3 - 6 x 8 ÷ 4 + 14
   ? = 13 + 3 -6 x 8/4 + 14
   ? = 13 + 3 - 12 + 14
   ? = 30 - 12
   ? = 18
