If X stands for addition, V stands for substraction, U stands for 'equal to', ∧ stands for division, ∑ stands for multiplication, O stands for greater than and σ stands for less than. State which expression is true?
If X stands for addition, V stands for substraction, U stands for 'equal to', ∧ stands for division, ∑ stands for multiplication, O stands for greater than and σ stands for less than. State which expression is true? Correct Answer <p>13 V 12 X 9 V 2 O 5 ∑ 1</p>
The logic followed here is :
| Symbol | Meaning |
| X | + |
| V | - |
| U | = |
| ∧ | ÷ |
| ∑ | × |
| O | > |
| σ | < |
Option 1)
3 X 8 V 2 U 12 ∧ 3
3 + 8 - 2 = 12 ÷ 3
11 - 2 = 4
9 ≠ 4
So '3 X 8 V 2 U 12 ∧ 3' is not true.
Option 2)
13 V 12 X 9 V 2 O 5 ∑ 1
13 - 12 + 9 - 2 > 5 × 1
22 - 12 - 2 > 5
8 > 5
So '13 V 12 X 9 V 2 υ 5 ∑ 1' is true.
Option 3)
2 ∑ 3 ∑ 4 σ 51 ∧ 3
2 × 3 × 4 < 51 ÷ 3
24 < 17
So '2 ∑ 3 ∑ 4 σ 51 ∧ 3' is not true.
Option 4)
3 ∑ 2 ∑ 4 U 2 X 7 V 3
3 × 2 × 4 = 2 + 7 - 3
24 = 6
So '3 ∑ 2 ∑ 4 U 2 X 7 V 3' is not true.
Thus only option 2 is true
Hence, the correct answer is "Option 2".
