Question

Answer 1

Answer:

Hi

Happy Republic Day

Do you remember me.

How are you??

Answer 2

Answer:

2.5 days

Step-by-step explanation:

Work done by Aakash in one day=1/20

Work done by Rohit in one day=1/25

Work done by both of them in one day= 1/20+1/25= 9/100

Work done by both in 10 days= 9/100×10=9/10

Work that Rohit has to do alone= 1/10

Work done by Rohit in one day-----1/25

Work done by Rohit in x days-----1/10

By cross multiplication, x/25=1/10

x/5=1/2

x=5/2= 2.5 days

Therefore, Rohit takes 2days and 12 hours to finish the work
