deep pit. Every day it climbs 5 metres a
but at night slide down by 400 cm. How many
days will it take to reach the top of the
pit
option
15. 16. 17. 18.
​

Answer 1

Answer:

Step-by-step explanation: We can solve this very easily!

Depth of pit = 20m

Distance snail climbs in 1 day = 5m

Distance it slides down in 1 day= 400cm

Actual distance the snail climbs = 5m - 400 cm = 1m/100cm

Now,

20m = 2000cm

2000cm/100cm = 20 days

P.S this option is not there in your question, but 20 days is correct!
