Answers
Given : Rani distributed chocolates to her friends on her Birthday.
If she gives 7 chocolates to each friend, one friend will get only 4 chocolates.
if she gives 4 chocolates, she will be left with 30 chocolates.
To Find : How many friends does she have
Solution:
Let say there are n friends
If she gives 7 chocolates to each friend, one friend will get only 4 chocolates.
Hence n-1 friends will get 7 chocolates and 1 will get 4 chocolates.
Hence total chocolates = 7(n - 1) + 4
= 7n - 3
if she gives 4 chocolates, she will be left with 30 chocolates.
Hence total chocolates = 4n + 30
Equate both
7n - 3 = 4n + 30
=> 3n = 33
=> n = 11
Hence she has 11 friends
