दिया गया समीकरण: 13 − 780 × 12 ÷ 16 + 32 = ?

दी गई जानकारी को विकूटित करने पर:

मूल चिह्न + - × ÷
नया चिह्न - × ÷ +

 

अब, समीकरण में चिह्नों को बदलने पर:

⇒ 13 × 780 ÷ 12 + 16 - 32 = ?

BODMAS नियम लागू करने पर:

⇒ 13 × 780 ÷ 12 + 16 - 32 = ?

13 × 65 + 16 - 32 = ?

845 + 16 - 32 = ?

861 - 32 = ?

829 = ?

इसलिए, सही उत्तर "विकल्प 4" है।
