Question & Answer (English)
What will come in place of the question mark (?) in the following equation, if '+' and '–' are interchanged and '$\times$' and '$\div$' are interchanged?
$1604 \times 4 - 525 \div 5 + 73 = ?$

According to the question, we need to interchange the signs as follows:
- Replace '$\times$' with '$\div$'
- Replace '$\div$' with '$\times$'
- Replace '$+$' with '$-$'
- Replace '$-$' with '$+$'
Original Equation: $1604 \times 4 - 525 \div 5 + 73$
New Equation after interchange:
$1604 \div 4 + 525 \times 5 - 73$
Now, applying the BODMAS rule (Brackets, Order, Division, Multiplication, Addition, Subtraction):
- Division: $1604 \div 4 = 401$
- Multiplication: $525 \times 5 = 2625$
- Equation becomes: $401 + 2625 - 73$
- Addition: $401 + 2625 = 3026$
- Subtraction: $3026 - 73 = 2953$
So, the correct answer is 2953.
प्रश्न एवं उत्तर (हिंदी)
यदि '+' और '–' को आपस में बदल दिया जाए और '$\times$' और '$\div$' को आपस में बदल दिया जाए, तो निम्नलिखित समीकरण में प्रश्न चिह्न (?) के स्थान पर क्या आएगा?
$1604 \times 4 - 525 \div 5 + 73 = ?$
- 2953 — सही उत्तर
- 2935
- 2539
- 2395
प्रश्न के अनुसार, हमें चिह्नों को आपस में बदलना होगा:
- '$\times$' की जगह '$\div$' रखें।
- '$\div$' की जगह '$\times$' रखें।
- '$+$' की जगह '$-$' रखें।
- '$-$' की जगह '$+$' रखें।
नया समीकरण:
$1604 \div 4 + 525 \times 5 - 73$
अब, BODMAS नियम का पालन करते हुए इसे हल करते हैं:
- भाग (Division): $1604 \div 4 = 401$
- गुणा (Multiplication): $525 \times 5 = 2625$
- अब समीकरण है: $401 + 2625 - 73$
- जोड़ (Addition): $401 + 2625 = 3026$
- घटाव (Subtraction): $3026 - 73 = 2953$
अतः, सही उत्तर 2953 है।
