| Option | ÷, ×, −, =, + | incorrect |
| Option | ÷, ×, −, +, = | correct |
| Option | ÷, −, ×, =, + | incorrect |
| Solution | 221 * 17 * 12 * 130 * 24 * 50 Take option C, 221 ÷ 17 × 12 – 130 + 24 = 50 LHS = 221 ÷ 17 × 12 – 130 + 24 = 13 × 12 – 130 + 24 = 156 – 130 + 24 = 50 LHS = RHS Hence, option C is correct. | |
