| Type | multiple_choice | |
| Option | 12 – 30 x 18 ÷ 3 + 16=174 | incorrect |
| Option | 14 x 5 – 18 ÷ 6 + 30=73 | incorrect |
| Option | 35 ÷ 5 x 5 + 30 – 18=23 | correct |
| Option | 64 + 18 x 5 ÷ 3 – 30=98 | incorrect |
| Solution | 35 ÷ 5 x 5 + 30 – 18 = 23 After interchanging the digit, we get : => 35 ÷ 5 x 5 + 18 – 30 = 23 => 7 x 5 + 18 – 30 = 23 => 35 + 18 – 30 = 23 => 53 – 30 = 23 => 23 = 23 LHS = RHS | |
