Question

a boy has some toffees he gave 1/3 of it to his sister and in the remaining gave 1/2 of it to his brother and is now left with 20 toffees how many did he have at first

Answer 1

Answer:

Step-by-step explanation:

Let the no. Of toffees the boy has be x

So, toffees he gave to his sister=1/3 of x

Amount of toffees left with him=x-1/3×x= 2x/3

He gives half of it to his brother

So he gives his brother=1/2 of 2x/3

Amount of toffees he has with him now=x/3

Amount of toffees he has with him=20 toffees.

So, x/3=20

=60 toffees.

Thus, he had 60 toffees with him in the beginning.
