Answer 2

ans===Length of First candle = 25 cm

Length of second candle = 25+5= 30 cm

we have to take one of things in fraction and the things which are related to them in direct porportion in fraction.

Let another time which is not given be X

= 25/30  = 45/X

=  X   =   (45/25)30

=  X   =    54
