Detailed Solution
Download Solution PDF1. ÷ आणि +
117 + 13 ÷ 16 × 540 - 40 = 644
⇒ 117 + 0.8125 × 540 - 40 = 644
⇒ 117 + 438.75 - 40 = 644
⇒ 555.75 - 40 = 644
⇒ 515.75 - 40 ≠ 644
2. + आणि ×
117 ÷ 13 × 16 + 540 - 40 = 644
⇒ 9 × 16 + 540 - 40 = 644
⇒ 144 + 540 - 40 = 644
⇒ 684 - 40 = 644
⇒ 644 = 644
3. - आणि +
117 ÷ 13 - 16 × 540 + 40 = 644
⇒ 9 - 8640 + 40 = 644
⇒ 49 - 8640 = 644
⇒ -8591 ≠ 644
4. ÷ आणि -
117 - 13 + 16 × 540 ÷ 40 = 644
⇒ 117 - 13 + 16 × 13.5 = 644
⇒ 117 - 13 + 216 = 644
⇒ 333 - 13 = 644
⇒ 320 ≠ 644
म्हणून, ‘+ आणि ×’ हे योग्य उत्तर आहे.
