Correct option is A
Given
321 * 3 * 236 * 5 * 248 * 4 * 20 = 384
Using the signs +, -, ×, +, ÷, × in place of * and apply BODMAS rule.
321 + 3 – 236 × 5 + 248 ÷ 4 × 20 = 384
321 + 3 – 236 × 5 + 62 × 20 = 384
321 + 3 – 1180 + 1240 = 384
1564 – 1180 = 384
384 = 384
Therefore, the correct answer is (a).
