Question :

Directions: In the following question you have to identify the correct response from the given premises stated according to the following symbols.
Select the set of symbols that can be fitted correctly in the equation.
4....3....4 = 48

Option 1: +, +

Option 2: +, –

Option 3: ×, +

Option 4: ×, ×

Correct Answer: ×, ×

Solution : Given:
4....3....4 = 48

Let's check the options –
First option: +, +
⇒ 4 + 3 + 4 = 48
On solving the L.H.S. of the equation, we get –
= 4 + 3 + 4
= 11 ≠ 48
Second option: +, –
⇒ 4 + 3 – 4 = 48
On solving the L.H.S. of the equation, we get –
= 4 + 3 – 4
= 3 ≠ 48
Third option: ×, +
⇒ 4 × 3 + 4 = 48
On solving the L.H.S. of the equation, we get –
= 4 × 3 + 4
= 12 + 4
= 16 ≠ 48
Fourth option: ×, ×
⇒ 4 × 3 × 4 = 48
On solving the L.H.S. of the equation, we get –
= 4 × 3 × 4
= 48

Here, only the fourth option satisfies the R.H.S. of the given equation. Hence, the fourth option is correct.
