Seema can do the work in 16 days
⇒ 1 day = 1/16 of the work
Find the amount of work Reema can do in a day:
20% of 1/16 = 20/100 x 1/16 = 1/80
Amount of work done in a day = 1/16 - 1/80 = 1/20
Find the number of days Reema needed:
1/20 of the work = 1 day
20/20 of the work = 1 x 20 = 20 days
Answer: Reema needs 10 days
