Question

A one-foot tall tree was planted on New Year’s day. If there is a 10 per cent increase in its height every month with respect to the previous month, which of the following will be its height on All Fool’s Day (April 1)

Answer 1

Answer:

1.3 foot

Step-by-step explanation:

1 foot tall tree was planted on 1 January

its height increases 10% per month

its height on 1st February =

1 + 10/100 foot

= 110/100 foot

= 1.10 foot

its height on 1st march =

1.10 + 10/100

= 120/100 foot

= 1.20 foot

its height on 1st April =

1.20 + 10/100

= 130/100

= 1.3 foot
