What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged? 28 + 125 × 5 − 12 ÷ 3 = ?
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 चिन्ह (?) के स्थान पर क्या आएगा?
28 + 125 × 5 − 12 ÷ 3 = ?
Detailed Solution & Logic
Correct Answer:
39
Given expression:
$28 + 125 \times 5 - 12 \div 3$
Interchange the operators:
- $+$ becomes $-$
- $-$ becomes $+$
- $\times$ becomes $\div$
- $\div$ becomes $\times$
So the expression becomes:
$28 - 125 \div 5 + 12 \times 3$
Now solve using BODMAS:
$125 \div 5 = 25$
$12 \times 3 = 36$
So,
$28 - 25 + 36 = 3 + 36 = 39$
Final Answer: 39
