Detailed Solution
Download Solution PDFदिलेले आहे:
A एक कार्य 8 दिवसांत करू शकतो, तर B ते 18 दिवसांत करू शकतो.
वापरलेली संकल्पना:
कार्यक्षमता = (एकूण कार्य / घेतलेला एकूण वेळ)
कार्यक्षमता = एका दिवसात केलेले कार्य
गणना:
एकूण कार्य 72 एकक आहे असे मानू (8 आणि 18 चा लसावि)
A ची कार्यक्षमता 72 / 8 = 9 एकक आहे
B ची कार्यक्षमता 72 / 18 = 4 एकक आहे
2 दिवसांत ते 9 + 4 = 13 एकक करतात
ते 65 एकक काम करतात 5 × 2 = 10 दिवसांत
तर B हा 1 दिवसांत 4 एकक करतो
तर A हा 1/3 दिवसांत 3 एकक करतो
एकूण दिवसांची संख्या 10 + 1 + 1/3 = 11\(\frac{1}{3}\) असेल
