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
(15 – 10) ÷ (130 + 10) × 50 = ?
Option 1: 1800
Option 2: 113
Option 3: 2000
Option 4: 123
Correct Answer: 113
Solution :
Given:
× means –; – means ×; + means ÷ and ÷ means +.
(15 – 10) ÷ (130 + 10) × 50 = ?
After replacing the symbols, the equation becomes –
= (15 × 10) + (130 ÷ 10) – 50
= 150 + 13 – 50
= 163 – 50
= 113
So, 113 is the answer to the given equation. Hence, the second option is correct.
