BODMAS नियम की सहायता से समीकरण को हल किया गया है:
प्रत्येक विकल्प की एक-एक करके जाँच करने पर,
विकल्प 1) -, ÷, ×, =
⇒ 23 - 2 ÷ 2 × 5 = 18
⇒ 23 - 1 × 5 = 18
⇒ 23 - 5 = 18
⇒ 18 = 18
⇒ बायाँ पक्ष = दायाँ पक्ष
विकल्प 2) -, ÷, +, =
⇒ 23 - 2 ÷ 2 + 5 = 18
⇒ 23 - 1 + 5 = 18
⇒ 28 - 1 = 18
⇒ 27 ≠ 18
⇒ बायाँ पक्ष ≠ दायाँ पक्ष
विकल्प 3) -, ÷, =, +
⇒ 23 - 2 ÷ 2 = 5 + 18
⇒ 23 - 1 = 5 + 18
⇒ 22 ≠ 23
⇒ बायाँ पक्ष ≠ दायाँ पक्ष
विकल्प 4) -, ×, ÷, =
⇒ 23 - 2 × 2 ÷ 5 = 18
⇒ 23 - 2 × 0.4 = 18
⇒ 23 - 0.8 = 18
⇒ 22.2 ≠ 18
⇒ बायाँ पक्ष ≠ दायाँ पक्ष
अतः, सही उत्तर "विकल्प 1" है।
