Solution
The correct option is D3 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

= 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.
