Question : Directions: In the following question, you have to identify the correct response from the given premises stated according to the following symbols. If + stands for multiplication, – stands for division, × stands for addition, and ÷ stands for subtraction, then which one of the following equations is correct?
Option 1: 12 × 5 + 4 – 5 ÷ 4 = 20
Option 2: 12 ÷ 5 + 4 – 5 × 4 = 18
Option 3: 12 + 5 – 4 × 5 ÷ 4 = 16
Option 4: 12 ÷ 5 – 4 × 5 + 4 = 22
Correct Answer: 12 + 5 – 4 × 5 ÷ 4 = 16
Solution : Given: + stands for multiplication, – stands for division, × stands for addition, and ÷ stands for subtraction.
Replace the mathematical signs and solve the equations. Let's check the given options – First option: 12 × 5 + 4 – 5 ÷ 4 = 20 ⇒ 12 + 5 × 4 ÷ 5 – 4 = 20 Solving L.H.S. of the equation – = 12 + 5 × 0.8 – 4 = 12 + 4 – 4 = 16 – 4 = 12 ≠ 20 Second option: 12 ÷ 5 + 4 – 5 × 4 = 18 ⇒ 12 – 5 × 4 ÷ 5 + 4 = 18 Solving L.H.S. of the equation – = 12 – 5 × 0.8 + 4 = 12 – 4 + 4 = 16 – 4 = 12 ≠ 18 Third option: 12 + 5 – 4 × 5 ÷ 4 = 16 ⇒ 12 × 5 ÷ 4 + 5 – 4 = 16 Solving L.H.S. of the equation – = 12 × 1.25 + 5 – 4 = 15 + 5 – 4 = 20 – 4 = 16 = R.H.S. Fourth option: 12 ÷ 5 – 4 × 5 + 4 = 22 ⇒ 12 – 5 ÷ 4 + 5 × 4 = 22 Solving L.H.S. of the equation – = 12 – 1.25 + 5 × 4 = 12 – 1.25 + 20 = 32 – 1.25 = 30.75 ≠ 22
So, only the equation in the third option satisfies the given conditions. Hence, the third option is correct.
