Detailed Solution
Download Solution PDFदिया गया समीकरण : 3 × 12 - 6 ÷ 2 + 12 = 16
प्रश्न के अनुसार, चिह्नों को परस्पर परिवर्तित करने के बाद:
इसलिए,
- विकल्प - (1) : ÷ और +
3 × 12 - 6 ÷ 2 + 12 = 16 ⇒ 3 × 12 - 6 + 2 ÷ 12 = 16
3 × 12 - 6 + 0.16 = 16
36 + 0.16 - 6 = 16
36.16 - 6 = 16
30.16 ≠ 16 (बाएँ पक्ष ≠ दाएँ पक्ष)
- विकल्प - (2) : × और ÷
3 × 12 - 6 ÷ 2 + 12 = 16 ⇒ 3 ÷ 12 - 6 × 2 + 12 = 16
0.25 - 6 × 2 + 12 = 16
0.25 +12 - 12 = 16
12.25 - 12 = 16
0.25 ≠ 16 (बाएँ पक्ष ≠ दाएँ पक्ष)
- विकल्प - (3) : - और ÷
3 × 12 - 6 ÷ 2 + 12 = 16 ⇒ 3 × 12 ÷ 6 - 2 + 12 = 16
3 × 2 - 2 + 12 = 16
6 + 12 - 2 = 16
18 - 2 = 16
16 = 16 (बाएँ पक्ष = दाएँ पक्ष)
- विकल्प - (4) : - और +
3 × 12 - 6 ÷ 2 + 12 = 16 ⇒ 3 × 12 + 6 ÷ 2 - 12 = 16
3 × 12 + 3 - 12 = 16
36 + 3 - 12 = 16
39 - 12 = 16
27 ≠ 16 (बाएँ पक्ष ≠ दाएँ पक्ष)
