Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
आरिफ, अरुण आणि अब्राहम अनुक्रमे 12, 20 आणि 24 दिवसात एक काम करू शकतात.
ते सर्व एकत्र काम सुरू करतात. अरुण काम पूर्ण होण्याच्या 3 दिवस आणि अब्राहम 6 दिवस आधी काम सोडतो.
वापरलेली संकल्पना:
एकूण काम = कार्यक्षमता x वेळ
गणना:
त्यांनी घेतलेला एकूण वेळ x दिवस आहे असे समजा
आता,
12, 20, आणि 24 चे लसावि = 120 म्हणजेच एकूण काम
तर, आरिफची कार्यक्षमता = 120/12
⇒ 10
अरुणची कार्यक्षमता = 120/20
⇒ 6
अब्राहमची कार्यक्षमता = 120/24
⇒ 5
प्रश्नानुसार,
x × 10 + (x - 3) × 6 + (x - 6) × 5 = 120
⇒ 10x + 6x - 18 + 5x - 30 = 120
⇒ 21x = 120 + 48
⇒ 21x = 168
⇒ x = 8
∴ आवश्यक वेळ 8 दिवस आहे.
