Question :

Directions: In the following question, you have to identify the correct response from the given premises stated according to the following symbols.
In certain codes 0, 1, 2,........, 9 is coded as a, b, c,.........., j then find baf ÷ bf × d.

Option 1: cb

Option 2: d

Option 3: df

Option 4: be

Correct Answer: cb

Solution :

Given:
Code 0, 1, 2,........, 9 is coded as a, b, c,.........., j

From the above-given codes, find the code of baf ÷ bf × d;
b = 1; a = 0; f = 5; d = 3
Now, put the above codes in baf ÷ bf × d –
= baf ÷ bf × d
= 105 ÷ 15 × 3
= 7 × 3
= 21
Now, c = 2; b = 1

Thus, 21 is the code of cb. Hence, the first option is correct.
