Detailed Solution
Download Solution PDF1. – and +
588 ÷ 28 × 32 - 72 + 160 = 760
⇒ 21 × 32 - 72 + 160 = 760
⇒ 672 - 72 + 160 = 760
⇒ 832 - 72 = 760
⇒ 760 = 760
2. ÷ and –
588 - 28 × 32 + 72 ÷ 160 = 760
⇒ 588 - 896 + 0.45 = 760
⇒ 588.45 - 896 = 760
⇒ -307.55 ≠ 760
3. + and ×
588 ÷ 28 + 32 × 72 – 160 = 760
⇒ 21 + 2304 - 160 = 760
⇒ 2325 - 160 = 760
⇒ 2165 ≠ 760
4. ÷ and +
588 + 28 × 32 ÷ 72 – 160 = 760
⇒ 588 + 28 × 0.45 - 160 = 760
⇒ 588 + 12.6 - 160 = 760
⇒ 600.6 - 160 = 760
⇒ 440.6 ≠ 760
Hence, '– and +' is the correct answer.
