What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
यदि ‘+’ और ‘−’ को परस्पर बदल दिया जाए तथा ‘×’ और ‘÷’ को परस्पर बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न-चिह्न (?) के स्थान पर क्या आएगा?
26 × 2 − 21 + 7 ÷ 4 = ?
Detailed Solution & Logic
Correct Answer:
6
Step 1: चिन्हों को बदलें
दिया है:
26 × 2 − 21 + 7 ÷ 4
अब चिन्ह बदलेंगे:
- × ↔ ÷
- + ↔ −
👉 नया समीकरण बनेगा:
26 ÷ 2 + 21 − 7 × 4
Step 2: BODMAS के अनुसार हल करें
26 ÷ 2 + 21 − 7 × 4
= 13 + 21 − 28
= 34 − 28
= 6
Final Answer:
👉 6 (सही विकल्प: 2)
