Converting Question in English

A can do a work in 30 days. He worked for 6 days and B completed the remaining work in 48 days. B alone can complete the entire work in?

Solution in Hindi:-

A 30 दिनों में काम करता है|

तो, इक दिन का काम = 1/30

और 6 दिन का काम = \tt 6 \times \dfrac{1}{30} = \dfrac{1}{5}

शेष कार्य = 4/5

B द्वारा किया गया कार्य

4/5 काम = 48  दिन

पूरा काम =  48 \times \dfrac{5}{4} =60दिन

आपका उत्तर विकल्प A है

Solution in English:-

A can complete work in 30days

So, 1 day work = 1/30

And six day work = \tt 6 \times \dfrac{1}{30} =\dfrac{1}{5}

Left work = 1 - 1/5 =4/5

ATQ, 4/5 part of work is done by B

So, 4/5 part of Work by B = 48days

So, Full work= \tt 48 \times \dfrac{5}{4} =60days

So, Option A is correct
