Mathematical Operations - Letter Substitution With Digits
Letter Substitution with Digits: In these type of problems the letters have been written in place of symbols for example the digit 1 may be written as x, the candidate has to perform substitution and then solve the question accordingly to reach the desired result.
Illustration: If in an imaginary language, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 are substituted respectively by a, b, c, d, e, f, g, h , i and j, and 10 is written as ba, then find the value of
A. 684 B. 816 C. 916 D. 1564
Answer: B
Solution: Using the information provided in the question, the given expression c is replaced with 2, d is replaced with 3 and so on . the statement becomes as follow
Hence, the correct choice is B.
If the digits 0,1, 2, 3, 4, 5, 6, 7, 8 and 9 are substituted respectively by a, b, c, d, e, f, g, h, i and j so that 135 is written as b d f, then (e f × f - b a) ÷ e d is equal to | |||
