Answers
Answer:
47 is the answer
Step-by-step explanation:
Given : Rani distributed chocolates to her friends on her Birthday.
If she gives 3 chocolates to each friend, one friend will get only 1 chocolates.
if she gives 2 chocolates, she will be left with 13 chocolates.
To Find : How many friends does she have
Solution:
Let say there are n friends
If she gives 3 chocolates to each friend, one friend will get only 1 chocolates.
Hence n-1 friends will get 3 chocolates and 1 will get 1 chocolates.
Hence total chocolates = 3(n - 1) + 1
= 3n - 2
if she gives 2 chocolates, she will be left with 13 chocolates.
Hence total chocolates = 2n + 13
Equate both
3n - 2 = 2n + 13
=> 5n = 15
=> n = 3
Hence she has 3 friends
3n - 2 = 7 chocolates
