SSC CHSL 202110)P can complete five-eighths of a work in 15 days and Q can complete three-fourths of the same work in 30 days. They worked together for 8 days and then P left. How much time will Q working alone, take to complete the remaining work?

Correct Option: C

18 days 16 hours

P alone can complete work in = 15 × 8/5 = 24 days

Q alone can complete work in = 30 × 4/3 = 40 days

Let work done alone by Q to complete work be x, then 8/24 + (8+x)/40 = 1

x = 56/3 days which is equal to 18 days and 16 hours
