||✪✪ प्रश्न ✪✪||

  • (A + B) दोनों मिलकर कुल काम करते है = 20 दिन में ll
  • A अकेला काम करता है = 10 दिन ll
  • B बचा हुआ काम करता है = 25 दिन में ll

|| ✰✰ उतर ✰✰ ||

→ (A + B) का एक दिन का काम = (1/20)

प्रश्नानुसार :-

→ 10A + 25 B = 1

→ 10A + 10B + 15B = 1

→ 10(A + B) + 15B = 1

(A + B) का एक दिन का काम = (1/20) रखने पर ,

→ 10 * (1/20) + 15B = 1

→ 15B = 1 - 1/2

→ 15B = 1/2

→ B = 1/(2*15)

→ B = 1/30

→ B = 30 दिन ll

अत: B अकेला उस काम को 30 दिन में कर देगा l
