Detailed Solution
Download Solution PDFBODMAS नियम के अनुसार,
+ और -, 7 और 6 के चिह्नों को एक-एक करके आपस में बदलने पर
1) 4 × 7 + 6 – 3 ÷ 1 = 20
4 × 6 - 7 + 3 ÷ 1 = 20
4 × 6 - 7 + 3 = 20
24 - 7 + 3 = 20
27 - 7 = 20
20 = 20
2) 8 × 7 + 5 ÷ 1 – 6 = 17
8 × 6 - 5 ÷ 1 + 7 = 17
48 - 5 + 7 = 17
50 ≠ 17
3) 7 - 6 × 3 + 4 ÷ 1 = 8
6 + 7 × 3 - 4 ÷ 1 = 8
6 + 21 - 4 = 8
23 ≠ 8
4) 7 × 2 – 6 + 4 ÷ 2 = 13
6 × 2 + 7 - 4 ÷ 2 = 13
12 + 7 - 2 = 13
17 ≠ 13
अतः , सही उत्तर "विकल्प 1" है ।
