Question : Directions: In the following question you have to identify the correct response from the given premises stated according to the following symbols:
If × means +, + means ÷, – means ×, and ÷ means –, then
6 × 4 – 5 + 2 ÷ 1 = ?
Option 1: 11
Option 2: 15
Option 3: 10
Option 4: 12
Correct Answer: 15
Solution :
Given:
× means +, + means ÷, – means ×, and ÷ means –.
6 × 4 – 5 + 2 ÷ 1 = ?
On replacing the symbols with the mathematical signs, we get –
= 6 + 4 × 5 ÷ 2 – 1
= 6 + 4 × 2.5 – 1
= 6 + 10 – 1
= 16 – 1
= 15
So, 15 is the answer to the given equation. Hence, the second option is correct.
