Detailed Solution
Download Solution PDFदिया गया समीकरण: 17 * 11 * 42 * 2 * 7 = 18
प्रश्न के अनुसार * चिह्नों को बदलने पर:
इसलिए,
- विकल्प - (1) : - + ÷ ÷
17 - 11 + 42 ÷ 2 ÷ 7 = 18
17 - 11 + 21 ÷ 7 = 18
17 + 3 - 11 = 18
20 - 11 = 18
9 ≠ 18 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (2) : - + × ÷
17 - 11 + 42 × 2 ÷ 7 = 18
17 - 11 + 42 × 0.28 = 18
17 + 12 - 11 = 18
29 - 11 = 18
18 = 18 (बायाँ पक्ष = दायाँ पक्ष)
- विकल्प - (3) : - + × ×
17 - 11 + 42 × 2 × 7 = 18
17 + 588 - 11 = 18
605 - 11 = 18
594 ≠ 18 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (4) : + - + ×
17 + 11 - 42 + 2 × 7 = 18
17 + 11 + 14 - 42 = 18
42 - 42 = 18
0 ≠ 18 (बायाँ पक्ष ≠ दायाँ पक्ष)
