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".
