Correct Answer: 100 + 5 – 10 × 250 ÷ 200 = 100
Solution : Given: – stands for division, + stands for multiplication, ÷ stands for subtraction, and × stands for addition.
Replace the mathematical signs in the equations and solve the equations one by one.
Let's check the given options – First option: 100 + 5 – 10 × 250 ÷ 200 = 100 ⇒ 100 × 5 ÷ 10 + 250 – 200 = 100 Solving L.H.S. of the equation – = 100 × 0.5 + 250 – 200 = 50 + 250 – 200 = 300 – 200 = 100 = R.H.S. Second option: 200 + 10 – 20 × 200 ÷ 100 = 150 ⇒ 200 × 10 ÷ 20 + 200 – 100 = 150 Solving L.H.S. of the equation – = 200 × 0.5 + 200 – 100 = 100 + 200 – 100 = 300 – 100 = 200 ≠ 150 Third option: 50 × 5 ÷ 10 + 100 – 75 = 50 ⇒ 50 + 5 – 10 × 100 ÷ 75 = 50 Solving L.H.S. of the equation – = 50 + 5 – 10 × 1.33 = 50 + 5 – 13.3 = 55 – 13.3 = 41.7 ≠ 50 Fourth option: 300 + 5 – 20 × 200 ÷ 100 = 200 ⇒ 300 × 5 ÷ 20 + 200 – 100 = 200 Solving L.H.S. of the equation – = 300 × 0.25 + 200 – 100 = 75 + 200 – 100 = 275 – 100 = 175 ≠ 200
So, only the first option satisfies the given condition. Hence, the first option is correct.
