Detailed Solution
Download Solution PDFदिया गया कथन: 10 - 4 + 13 ÷ 15 × 3 = 71
प्रश्नानुसार, चिह्नों को बदलने के बाद:
इसलिए,
- विकल्प - (1) : + और ×
10 - 4 + 13 ÷ 15 × 3 = 71 ⇒ 10 - 4 × 13 ÷ 15 + 3 = 71
10 - 4 × 0.87 + 3 = 71
10 + 3 - 3.48 = 71
13 - 3.48 = 71
9.52 ≠ 71 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (2) : - और ÷
10 - 4 + 13 ÷ 15 × 3 = 71 ⇒ 10 ÷ 4 + 13 - 15 × 3 = 71
2.5 + 13 - 15 × 3 = 71
2.5 + 13 - 45 = 71
15.5 - 45 = 71
29.5 ≠ 71 (बायाँ पक्ष ≠ दायाँ पक्ष)
- विकल्प - (3) : ÷ और ×
10 - 4 + 13 ÷ 15 × 3 = 71 ⇒ 10 - 4 + 13 × 15 ÷ 3 = 71
10 - 4 + 13 × 5 = 71
10 + 65 - 4 = 71
75 - 4 = 71
71 = 71 (बायाँ पक्ष = दायाँ पक्ष)
- विकल्प - (4) : - और ×
10 - 4 + 13 ÷ 15 × 3 = 71⇒ 10 × 4 + 13 ÷ 15 - 3 = 71
10 × 4 + 0.87 - 3 = 71
40 + 0.87 - 3 = 71
40.87 - 3 = 71
37.87 ≠ 71 (बायाँ पक्ष ≠ दायाँ पक्ष)
