To do a certain work, A and B work
To do a certain work, A and B work on alternate days with B beginning the work on the first day. A alone can complete the same work in 22 days. If the work gets completed in \(11\frac{1}{2}\) days, then B alone can complete \(\frac{3}{4}\) the part of the original work in:
किसी निश्चित कार्य को करने के लिए, A और B बारी – बारी से एक – एक दिन छोडंकर कार्य करते हैं, जिसमें B पहले दिन कार्य करना शुरु करता है। A अकेले उस कार्य 22 दिनों में पूरा कर ,सकता हैं। यदि कार्य \(11\frac{1}{2}\) दिनों में पूरा हो जाता है, तो B अकेले मूल कार्य का \(\frac{3}{4}\) भाग कितने दिनों में पूरा करेगा?
Detailed Solution & Logic
six days / छह दिन
$ A=\dfrac{1}{22} $
Total days = $ \dfrac{23}{2} $
B works $ 6\text{ days, A works }5\dfrac{1}{2}\text{ days} $
Work by A=$ \dfrac{11}{2}\times\dfrac{1}{22}=\dfrac{1}{4} $
Work by B=$ \dfrac{3}{4}\text{ in }6\text{ days} $
Answer = 6 days
