Answer 1

Answer:

YOUR QUESTION :

Rohan has a certain no. Of chocolates if he gave 1/3 to his brother and 1/6 to friend. And left with 30 chocolates.

SOLUTION :

Let the total number of chocolates with Rahil be x.

No. of chocolates given to brother = x/3

No. of chocolates given to friend = x/6

No. of chocolates remaining with Rahil = 30

x = x/3 + x/6 + 30

=> - 30 = x/3 + x/6 - x (Transposing 30 to LHS, becomes - 30 and transposing x to RHS, becomes - x)

=> 30 = - x/3 - x/6 + x

=> 30 = - 2x/6 - x/6 + 6x/6

=> 30 = 3x/6

=> 3x = 6 * 30

=> 3x = 180

=> x = 180/3

=> x = 60

Total no. of chocolates with Rahil = 6O

No. of chocolates given to brother = x/3 = 60/3 = 20

No. of chocolates given to freind = x/6 = 60/6 = 10

Answer 2

Answer:

x = 60;

No.of chocolates given to brother = 60/3

= 20

No.of chocolates given to friends = 60/6

= 10
