Question

If a 25 cm long candle burns for 45 minutes,how long will another candle of the same material and same thickness but 5cm longer than the previous one burn ?

Answer 1

Hey there !

Solution:

This sum can be solved using Ratio and Proportion method.

So 25 cm => 45 minutes then 30 cm => ? minutes

Let the amount of time taken be 'x'

=> 25 : 45 :: 30 : x

Product of Means = Product of Extremes

=> 25 × x = 45 × 30

=> 25 x = 1350

=> x = 1350 / 25

=> x = 54

Hence the time taken would be 54 minutes.

Hope my answer helped !

HELLO FRIEND HERE IS UR ANSWER

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
