Correct answer: (D) 17
D=−, C=+, B=×, A=÷. So 13 D 32 C 36 B 49 A 49 = 13 − 32 + 36×49÷49. By BODMAS, 36×49÷49 = 36 (left to right). So 13 − 32 + 36 = 17.

सही उत्तर: (D) 17
D=−, C=+, B=×, A=÷। अतः 13 D 32 C 36 B 49 A 49 = 13 − 32 + 36×49÷49। BODMAS नियम से, 36×49÷49 = 36 (बाएँ से दाएँ)। अतः 13 − 32 + 36 = 17।
