Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले विधान : 77 ÷ 7 − 2 × 3 + 3 = 4
प्रश्नानुसार, संख्यांची अदलाबदल केल्यानंतर :
तर,
- पर्याय - (1): 3 आणि 77
77 ÷ 7 − 2 × 3 + 3 = 4 ⇒ 3 ÷ 7 − 2 × 77 + 3 = 4
0.42 − 2 × 77 + 3 = 4
0.42 + 3 - 154 = 4
3.42 - 154 = 4
-150.58 ≠ 4 (डावी बाजू ≠ उजवी बाजू)
- पर्याय - (2): 3 आणि 7
77 ÷ 7 − 2 × 3 + 3 = 4 ⇒ 77 ÷ 3 − 2 × 7 + 3 = 4
25.67 − 2 × 7 + 3 = 4
25.67 + 3 - 14 = 4
28.67 - 14 = 4
14.67 ≠ 4 (डावी बाजू ≠ उजवी बाजू)
- पर्याय - (3): 2 आणि 4
77 ÷ 7 − 2 × 3 + 3 = 4 ⇒ 77 ÷ 7 − 4 × 3 + 3 = 2
11 − 4 × 3 + 3 = 2
11 + 3 - 12 = 2
14 - 12 = 2
2 = 2 (डावी बाजू = उजवी बाजू)
- पर्याय - (4): 2 आणि 7
77 ÷ 7 − 2 × 3 + 3 = 4 ⇒ 77 ÷ 2 − 7 × 3 + 3 = 4
38.5 − 7 × 3 + 3 = 4
38.5 + 3 - 21 = 4
35.5 - 21 = 4
14.5 ≠ 4 (डावी बाजू ≠ उजवी बाजू)
