Question
Neha and Priya are assigned a piece of work. Neha can
complete 8 units of work each day, while Priya can finish the whole task alone in 32 days. If the total work is 160 units, how many days will they need to complete the task together?Solution
ATQ,
Let, the time taken by Neha and Priya to do the work be ‘x’ days.
Units of work done by Priya in a day = 160/32 = 5 units
So, 160/x = 8 + 5 = 13
160 = 13x
x = 160/13
