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 division, ÷ stands for multiplication, × stands for subtraction, and –stands for addition, then which of the following expressions is correct?
Option 1: 18 × 6 + 7 ÷ 5 – 2 = 16
Option 2: 18 ÷ 6 × 7 + 5 – 2 = 22
Option 3: 18 ÷ 6 – 7 + 5 × 2 = 20
Option 4: 18 + 6 ÷ 7 × 5 – 2 = 18
Correct Answer: 18 + 6 ÷ 7 × 5 – 2 = 18
Solution : Given: + stands for division, ÷ stands for multiplication, × stands for subtraction, and –stands for addition.
Replace the mathematical signs and solve the equations. Let's check the given options – First option: 18 × 6 + 7 ÷ 5 – 2 = 16 ⇒ 18 – 6 ÷ 7 × 5 + 2 = 16 Solving L.H.S. of the equation – = 18 – 0.85 × 5 + 2 = 18 – 4.25 + 2 = 20 – 4.25 = 15.75 ≠ 16 Second option: 18 ÷ 6 × 7 + 5 – 2 = 22 ⇒ 18 × 6 – 7 ÷ 5 + 2 = 22 Solving L.H.S. of the equation – = 18 × 6 – 1.4 + 2 = 108 – 1.4 + 2 = 110 – 1.4 = 108.6 ≠ 22 Third option: 18 ÷ 6 – 7 + 5 × 2 = 20 ⇒ 18 × 6 + 7 ÷ 5 – 2 = 20 Solving L.H.S. of the equation – = 18 × 6 + 1.4 – 2 = 108 + 1.4 – 2 = 109.4 – 2 = 107.4 ≠ 20 Fourth option: 18 + 6 ÷ 7 × 5 – 2 = 18 ⇒ 18 ÷ 6 × 7 – 5 + 2 = 18 Solving L.H.S. of the equation – = 3 × 7 – 5 + 2 = 21 – 5 + 2 = 23 – 5 = 18 = R.H.S.
So, only the equation in the fourth option satisfies the given conditions. Hence, the fourth option is correct.
