दिलेल्याप्रमाणे:

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.
