# Difficult Pie Charts Solved QuestionData Interpretation Discussion

Common Information

Six friends — Anand, Bimal, Praveen, Kiran, Yashwanth and Rohan — availed a new SMS offer, according to which there will be no charges for the SMSs sent or received within the group. The following pie charts pertain to the details regarding the number of SMSs sent by these persons within the group during the month of October.

The first pie chart gives the break-up of total number of SMSs received by Anand from his five friends in October according to the friend from whom he received the SMSs and the second pie chart gives the break-up of the total SMSs sent by these five persons within the group (i.e., excluding Anand) in the same month according to the person sending the SMSs.

Assume that SMSs sent are received instantly and also the number of SMSs sent by each person is always an integer. For all the following questions, consider only the SMSs sent by the persons within the group in the month of October.

 Q. Common Information Question: 2/4 Who has sent the least percentage of his SMS to Anand’?
 ✖ A. Bimal ✖ B. Praveen ✖ C. Kiran ✔ D. Yashwanth

Solution:
Option(D) is correct

$= \dfrac{10}{100}× 3000$

$= 300$

Similarly messages received from Praveen, Kiran, Yashwanth and Rohan are 750, 600, 450 and 900 respectively.

Percentage of messages sent by Bimal to Anand:

$= \dfrac{300}{0.15N}$

$= \dfrac{2000}{N}$

Similarly, the values for Praveen, Kiran, Yashwanth and Rohan are:

$\dfrac{3750}{N}$, $\dfrac{3750}{N}$, $\dfrac{1850}{N}$ and $\dfrac{3750}{N}$

So It is the least for Yashwanth.
