Correct Answer: 77
Solution :
Given:
A stands for ÷, B stands for ×, C stands for +, D stands for –
79 C 15 A 5 B 3 D 11 = ?
Replace the letters with mathematical signs and the equation becomes –
= 79 + 15 ÷ 5 × 3 – 11

= 79 + 9 – 11
= 77
So, 77 is the required answer. Hence, the third option is correct.
