Correct Answer: – and +

Solution : Given:
588 ÷ 28 × 32 + 72 – 160 = 760

Interchange the mathematical signs given in the equation with the signs given in the options one by one –
First option: – and +
⇒ 588 ÷ 28 × 32 – 72 + 160 = 760
Solving L.H.S. of the equation –
= 21 × 32 – 72 + 160
= 672 – 72 + 160
= 760 = R.H.S.
Second option: ÷ and –
⇒ 588 – 28 × 32 + 72 ÷ 160 = 760
Solving L.H.S. of the equation –
= 588 – 28 × 32 + 0.45
= 588 – 896 + 0.45
= –307.55 ≠ 760
Third option: + and ×
⇒ 588 ÷ 28 + 32 × 72 – 160 = 760
Solving L.H.S. of the equation –
= 21 + 32 × 72 – 160
= 21 + 2304 – 160
= 2165 ≠ 760
Fourth option: ÷ and +
⇒ 588 + 28 × 32 ÷ 72 – 160 = 760
Solving L.H.S. of the equation –
= 588 + 28 × 0.44 – 160
= 588 + 12.32 – 160
= 440.32 ≠ 760

So, only the first option satisfies the given equation. Hence, the first option is correct.
