Solution

The correct option is D 3 mins and 12 secs
Time taken to put fondants on 25 cakes = 113 hrs = 1 hr + 13 hr

= 60 mins + 13×60 mins

(As 1 hr = 60 mins)

= 60 mins + 20 mins = 80 mins

Time taken to put fondants on one cake

=Time taken to place fondants on 25 cakes25

=8025=16×55×5=165=315 mins

= 3 mins + 15 mins

= 3 mins + 15×60 secs

= 3 mins + 12 secs

= 3 mins and 12 secs

Therefore, Camille takes 3 mins and 12 secs to put fondants on one cake.

(d) is the correct option.
