Detailed Solution
Download Solution PDF1. ÷ आणि -
912 ÷ 456 × 28 + 390 - 2 = 444
⇒ 2 × 28 + 390 - 2 = 444
⇒ 56 + 390 - 2 = 444
⇒ 446 - 2 = 444
⇒ 444 = 444
2. ÷ आणि +
912 - 456 × 28 ÷ 390 + 2 = 444
⇒ 912 - 456 × 28 ÷ 390 + 2 = 444
⇒ 912 - 456 × 0.071 + 2 = 444
⇒ 912 - 32.376 + 2 = 444
⇒ 914 - 32.376 = 444
⇒ 881.624 ≠ 444
3. - आणि +
912 + 456 × 28 - 390 ÷ 2 = 444
⇒ 912 + 456 × 28 - 195 = 444
⇒ 912 + 12768 - 195 = 444
⇒ 13680 - 195 = 444
⇒ 13485 ≠ 444
4. ÷ आणि ×
912 - 456 ÷ 28 + 390 × 2 = 444
⇒ 912 - 456 ÷ 28 + 390 × 2 = 444
⇒ 912 - 16.28 + 780 = 444
म्हणून, '÷ आणि -' हे योग्य उत्तर आहे.
