Download Solution PDFएक बैल एक खेत को 5 दिनों में जोत सकता है, और एक भैंस उसी खेत को 10 दिनों में जोत सकती है। 3 बैलों और 2 भैंसों को एक साथ मिलकर खेत जोतने में कितने दिन लगेंगे?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFबैल की कार्य दर = 1 खेत / 5 दिन = 1 / 5 खेत/दिन
भैंस की कार्य दर = 1 खेत / 10 दिन = 1 / 10 खेत/दिन
3 बैल = 3 × 1 / 5 = 3 / 5 खेत/दिन
2 भैंस = 2 × 1 / 10 = 2 / 10 = 1 / 5 खेत/दिन
कुल कार्य दर = (3 / 5) + (1 / 5) = 4 / 5 खेत/दिन
समय = कुल कार्य / कार्य दर = 1 खेत / (4/5 खेत/दिन) = 5 / 4 दिन = 1.25 दिन
इस प्रकार, सही उत्तर 1.25 दिन है।
