Question:
If \(+ \to -\), \(- \to \div\), \(\times \to +\), \(\div \to \times\), evaluate:
\((20 + 10) \div (8 – 4) \times 2 = \text{?}\)
यदि \(+ \to -\), \(- \to \div\), \(\times \to +\), \(\div \to \times\) है, तो मान ज्ञात कीजिए:
\((20 + 10) \div (8 – 4) \times 2 = \text{?}\)
Options:
- 15
- 20
- 25
- 22
- 15
- 20
- 25
- 22
Correct Answer: d)
Explanation:
Substituting signs:
\((20 – 10) \times (8 \div 4) + 2\)
\(= 10 \times 2 + 2 = 20 + 2 = 22\).
चिह्नों को बदलने पर:
\((20 – 10) \times (8 \div 4) + 2\)
\(= 10 \times 2 + 2 = 20 + 2 = 22\)।
