Let the work done by pooja be x
Let the work done by ritu. be y
So x + y = 17
2. Condition
3/4y + y = 17
7y = 68
y = 9.7 days
x + 9.7 = 17
x = 7.3 days
Let the work done by ritu. be y
So x + y = 17

The other answer is wrong because the questions says 17 and a half. Thedude just chucked the half into the ocean and carried on.
