Answer 2

Answer:

20,10

Step-by-step explanation:

Let the number of chocolates Rahul have be 'x'.

⇒ He gave (1/3) to his brother = (x/3).

⇒ He gave (1/6) to his friend = (x/6).

⇒ He then left with 30 chocolates.

Now,

x - x/3 - x/6 = 30

(6x - 2x - x)/6 = 30

3x/6 = 30

3x = 180

x = 60.

Therefore:

⇒ Chocolates he gave to his brother = 60/3 = 20.

⇒ Chocolates he gave to his friend = 60/6 = 10.

Hope this helps!
