1) 56 + 12 × 34 - 12 = 102
After replacing the symbols by their meaning, we get:
L.H.S = 56 - 12 ÷ 34 × 12
= 56 – 4.23
= 51.77 ≠ R.H.S
2) 8 ÷ 44 - 5 + 25 = 203
After replacing the symbols by their meaning, we get:
L.H.S = 8 + 44 × 5 - 25
= 8 + 220 – 25
= 228 – 25
= 203 = R.H.S
3) 112 × 44 - 12 + 10 = 46
After replacing the symbols by their meaning, we get:
L.H.S = 112 ÷ 44 × 12 - 10
= 2.54 × 12 – 10
= 30.54 – 10
= 20.54 ≠ R.H.S
4) 9 ÷ 64 - 2 × 6 = 54
After replacing the symbols by their meaning, we get:
L.H.S = 9 + 64 × 2 ÷ 6
= 9 + 21.33
= 30.33 ≠ R.H.S
Hence, ‘option 2’ is the correct answer.
