Correct Answer: ÷, ×, +
Solution : Given: 8 * 8 * 1 * 7 = 8
Let's check the options – First option: ×, ÷, + ⇒ 8 × 8 ÷ 1 + 7 = 8 Solving the L.H.S. of the equation – = 8 × 8 ÷ 1 + 7 = 8 × 8 + 7 = 64 + 7 = 71 ≠ 8 Second option: +, ÷, × ⇒ 8 + 8 ÷ 1 × 7 = 8 Solving the L.H.S. of the equation – = 8 + 8 ÷ 1 × 7 = 8 + 8 × 7 = 8 + 56 = 64 ≠ 8 Third option: ÷, ×, + ⇒ 8 ÷ 8 × 1 + 7 = 8 Solving the L.H.S. of the equation – = 8 ÷ 8 × 1 + 7 = 1 × 1 + 7 = 1 + 7 = 8 = R.H.S. Fourth option: +, ×, ÷ ⇒ 8 + 8 × 1 ÷ 7 = 8 Solving the L.H.S. of the equation – = 8 + 8 × 1 ÷ 7 = 8 + 8 × 0.14 = 8 + 1.14 = 9.14 ≠ 8
So, only the third option satisfies the R.H.S. of the given equation. Hence, the third option is correct.
