Sample BODMAS & Simplification questions with answers

Q1. Simplify: 18 ÷ 3 × 2 + 4 − 1

सरल करें: 18 ÷ 3 × 2 + 4 − 1

Answer: 15. Division and multiplication from left to right: 18 ÷ 3 = 6, 6 × 2 = 12. Then 12 + 4 − 1 = 15.
भाग और गुणा बाएँ से दाएँ: 18 ÷ 3 = 6, 6 × 2 = 12। फिर 12 + 4 − 1 = 15

Q2. Find the value of 45² − 15²

45² − 15² का मान ज्ञात करें।

1900
1770
1800
900

Answer: 1800. a² − b² = (a + b)(a − b) = 60 × 30 = 1800.
a² − b² = (a + b)(a − b) = 60 × 30 = 1800

Q3. Simplify: 23 + 5 × 8 − 20 ÷ 4

सरल करें: 23 + 5 × 8 − 20 ÷ 4

Answer: 58. BODMAS: first 5 × 8 = 40 and 20 ÷ 4 = 5. Then 23 + 40 − 5 = 58.
BODMAS: पहले 5 × 8 = 40 और 20 ÷ 4 = 5। फिर 23 + 40 − 5 = 58

Q4. Simplify: (21² − 11²) ÷ (21 − 11)

सरल करें: (21² − 11²) ÷ (21 − 11)

Answer: 32. a² − b² = (a + b)(a − b), so the result is a + b = 21 + 11 = 32.
a² − b² = (a + b)(a − b), अतः परिणाम a + b = 21 + 11 = 32

Q5. Simplify: (12 + 12) × 6 ÷ 6

सरल करें: (12 + 12) × 6 ÷ 6

Answer: 24. Bracket first: 12 + 12 = 24. Then 24 × 6 = 144, and ÷ 6 = 24.
पहले कोष्ठक: 12 + 12 = 24। फिर 24 × 6 = 144, और ÷ 6 = 24

Q6. Simplify: (12 + 4) × 3 ÷ 4

सरल करें: (12 + 4) × 3 ÷ 4

Answer: 12. Bracket first: 12 + 4 = 16. Then 16 × 3 = 48, and ÷ 4 = 12.
पहले कोष्ठक: 12 + 4 = 16। फिर 16 × 3 = 48, और ÷ 4 = 12

Q7. Simplify: (3 + 33) × 2 ÷ 6

सरल करें: (3 + 33) × 2 ÷ 6

Answer: 12. Bracket first: 3 + 33 = 36. Then 36 × 2 = 72, and ÷ 6 = 12.
पहले कोष्ठक: 3 + 33 = 36। फिर 36 × 2 = 72, और ÷ 6 = 12

Q8. Simplify: 27 + 6 × 4 − 15 ÷ 5

सरल करें: 27 + 6 × 4 − 15 ÷ 5

Answer: 48. BODMAS: first 6 × 4 = 24 and 15 ÷ 5 = 3. Then 27 + 24 − 3 = 48.
BODMAS: पहले 6 × 4 = 24 और 15 ÷ 5 = 3। फिर 27 + 24 − 3 = 48

Q9. Simplify: 55 + 7 × 4 − 6 × 8

सरल कीजिए: 55 + 7 × 4 − 6 × 8

Answer: 35. Multiply first: 7 × 4 = 28, 6 × 8 = 48. Then 55 + 28 − 48 = 35.
पहले गुणा: 7 × 4 = 28, 6 × 8 = 48। फिर 55 + 28 − 48 = 35।

Q10. Simplify: 37 + 5 × 7 − 8 × 7

सरल कीजिए: 37 + 5 × 7 − 8 × 7

Answer: 16. Multiply first: 5 × 7 = 35, 8 × 7 = 56. Then 37 + 35 − 56 = 16.
पहले गुणा: 5 × 7 = 35, 8 × 7 = 56। फिर 37 + 35 − 56 = 16।
