Correct Answer: 131
Solution :
Given:
83 C 7 B 539 A 49 D 29 = ?
After replacing the letters with the mathematical signs, the equation becomes –
= 83 + 7 × 539 ÷ 49 – 29
= 83 + 7 × 11 – 29
= 83 + 77 – 29
= 160 – 29
= 131
So, 131 is the required answer to the given equation. Hence, the first option is correct.
