Detailed Solution
Download Solution PDFदिलेले समीकरण: 440 × 10 - 330 + 100 ÷ 5 = 214
पर्याय(1): - आणि ÷
चिन्हे बदलल्यास,
440 × 10 ÷ 330 + 100 - 5 = 214
440 × 0.03030 + 100 - 5 = 214
13.33 + 100 - 5 = 214
113.33 - 5 = 214
108.33 ≠ 214
पर्याय (2): + आणि ÷
चिन्हे बदलल्यास,
440 × 10 - 330 ÷ 100 + 5 = 214
440 × 10 - 3.3 + 5 = 214
4400 - 3.3 + 5 = 214
4405 - 3.3 = 214
4401.7 ≠ 214
पर्याय (3): + आणि ×
चिन्हे बदलल्यास,
440 + 10 - 330 × 100 ÷ 5 = 214
440 + 10 - 330 × 20 = 214
440 + 10 - 6600 = 214
450 - 6600 = 214
-6150 ≠ 214
पर्याय (4): × आणि ÷
चिन्हे बदलल्यास,
440 ÷ 10 - 330 + 100 × 5 = 214
44 - 330 + 100 × 5 = 214
44 - 330 + 500 = 214
544 - 330 = 214
214 = 214
म्हणून, पर्याय (4) योग्य आहे.
