Question (English)

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

  1. 2953 ✓ Correct
  2. 2935
  3. 2539
  4. 2395
Explanation:

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):

  1. Division: $1604 \div 4 = 401$
  2. Multiplication: $525 \times 5 = 2625$
  3. Equation becomes: $401 + 2625 - 73$
  4. Addition: $401 + 2625 = 3026$
  5. Subtraction: $3026 - 73 = 2953$

So, the correct answer is 2953.

प्रश्न (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?
$1604 \times 4 - 525 \div 5 + 73 = ?$

  1. 2953
  2. 2935
  3. 2539
  4. 2395
स्पष्टीकरण:

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:

  1. भाग (Division): $1604 \div 4 = 401$
  2. गुणा (Multiplication): $525 \times 5 = 2625$
  3. अब समीकरण है: $401 + 2625 - 73$
  4. जोड़ (Addition): $401 + 2625 = 3026$
  5. घटाव (Subtraction): $3026 - 73 = 2953$

अतः, सही उत्तर 2953 है।
