Question

In each of the following questions, different alphabets stand for various symbols as indicated below
Addition: O Subtraction: M Multiplication: A Division: Q Equal to: X Greater than: Y Less than: Z
Out of the four alternatives given in these questions, only one is correct according to the above letter symbols. Identify the correct answer.
A: 3 O 2 X 2 Q I A 3 O 1
B: 6 M 2 Y 10 Q 2 A 3 O 1
C: 10 A 2 Z 2 A 10 Q 2
D: 10 A 2 Y 2 Q 1 A 10 Q 2

Answer 1

- Hint: Here, we will put the symbols in the place of alphabets in every given option one by one. After putting symbols, it will form an equation. Then we will solve and check the equation. And check which of the following given options is satisfied.

Complete step-by-step solution :
To check option A:
Putting the symbols in option A, we have
3 O 2 X 2 Q I A 3 O 1
3 + 2 = 2 ÷ 1 × 3 + 1(In place of O we put ‘+’, in place of M we put ‘-’,similarly we will put other given symbols accordingly)
This equation is not correct because we have no symbol for I.

To check option B:
Putting the symbols in option B, we have
6 M 2 Y 10 Q 2 A 3 O 1
6 – 2 > 10 ÷ 2 × 3 + 1
$\therefore 4 > 16$
This equation is incorrect.

To check option C:
Putting the symbols in option C, we have
10 A 2 Z 2 A 10 Q 2
$10 \times 2 < 2 \times 10 \div 2$
$\therefore 20 < 10$
This equation is also incorrect.

To check option D:
Putting the symbols in option D, we have
10 A 2 Y 2 Q 1 A 10 Q 2
10 × 2 > 2 ÷ 1 × 10 ÷ 2
$\therefore 20 > 10$
This equation is correct.

Therefore, Option D is correct.

Note:
In these types of questions we need to put the symbols in place of given alphabets in each option and check one by one whether it is satisfied or not. This is the only way to check the result, there are no mathematical ways to solve and check.
