ज्ञात कीजिए कि निम्न में से कौन-सा समीकरण सही नहीं होगा।
आइए एक-एक करके प्रत्येक विकल्प की जाँच करते हैं,
विकल्प 1) 8 × 3 ÷ 6 + 9 – 7 = 2
दिया गया है: 7 और 9
⇒ 8 × 3 ÷ 6 + 7 - 9 = 2
⇒ 8 × 0.5 + 7 - 9 = 2
⇒ 4 + 7 - 9 = 2
⇒ 11 - 9 = 2
⇒ 2 = 2
⇒ बायाँ पक्ष = दायाँ पक्ष
विकल्प 2) 7 + 6 - 9 × 4 ÷ 2 = 2
दिया गया है: 7 और 9
⇒ 9 + 6 - 7 × 4 ÷ 2 = 2
⇒ 9 + 6 - 7 × 2 = 2
⇒ 9 + 6 - 14 = 2
⇒ 15 - 14 = 2
⇒ 1 ≠ 2
⇒ बायाँ पक्ष ≠ दायाँ पक्ष
विकल्प 3) 9 + 4 × 3 – 7 ÷ 1 = 10
दिया गया है: 7 और 9
⇒ 7 + 4 × 3 – 9 ÷ 1 = 10
⇒ 7 + 4 × 3 - 9 = 10
⇒ 7 + 12 - 9 = 10
⇒ 19 - 9 = 10
⇒ 10 = 10
⇒ बायाँ पक्ष = दायाँ पक्ष
विकल्प 4) 9 × 3 + 4 ÷ 2 – 7 = 14
दिया गया है: 7 और 9
⇒ 7 × 3 + 4 ÷ 2 – 9 = 14
⇒ 7 × 3 + 2 - 9 = 14
⇒ 21 + 2 - 9 = 14
⇒ 23 - 9 = 14
⇒ 14 = 14
⇒ बायाँ पक्ष = दायाँ पक्ष
अतः, सही उत्तर "विकल्प 2" है।
