Letter Substitution: In these type of questions you are provided with certain letters representing the symbols. A statement is given, the candidate is reqired to substitute the letters with the symbols and perform the calculations.
Illustration: If L stands for +, M stands for -, N stands for X and P stands for , then 14 N 10 L 42 P 2 M 8 equals
A. 153 B. 216 C. 248 D. 251
Answer: A
Solution: Fisrt we will substitute the symbols in the place of letters. the expression becomes
Now we will solve it by using BODMAS
So, first solve for N and P
THen we will solve for + and -
= 161 - 8 = 153
Hence, the corrrect option is A.
