Question

There is a pond and at the center of it grows a beautiful lotus flower. the size of the lotus keeps on growing double each day. if you look after twenty days, the lotus will have covered the entire pond.

Answer 1

The lotus covers half of the pond in 19 days.

• All we need to do is to give attention to the line that the size of the lotus doubles every day.
• The lotus might have grown to half the size of the pond on the previous day, i.e, 19th because it has covered the entire pond in 20 days.

• So we can say that it will take 19 days for the lotus to cover half of the pond.

Answer 2

QUESTION:

There is a pond and at the center of it grows a beautiful lotus flower. The size of the lotus keeps on growing double each day. If you look after twenty days, the lotus will have covered the entire pond. How much time will the lotus take to cover half of the pond?

ANSWER:

The lotus will take 19 days to cover half of the pond.

• We can see that here, it is given, that the lotus grows to double each day.
• As the lotus grows to cover the full pond in 20 days. It means the lotus should have covered half the pond, the previous day.
• Now, the previous day to the 20th day would be the 19th day.
• Thus, the lotus will take 19 days to cover half of the pond.
