Question

a boy eats 25% of the cake and gives away 35% of it to his friends what % of cake is still left with him

Answer 1

Answer:

40%

Step-by-step explanation:

The boy has a 100% cake.

He eats 25% and gives away 35%.

So total percentage of cake given is 25=35=60%

Therefore the boy is left with 100-60=40% of cake.

Answer 2

Answer:

Let us assume the full volume of the cake gift is 100 %

First he fare 25% of the cake.

Remaining Portion of cake once eating

=> 100% -25% =75%

Now he gifts thirty fifth of cake to the current friend.

So,

=> 75% -35% =40%

Hence  

the remaining portion of cake is 40%
