The average presence of employees of a company for yoga sessions in an office on Monday, Tuesday and Wednesday is thirty two and on the Wednesday, Thursday, Friday and Saturday is thirty. If the average number of employees on all the six days is twenty six then the number of employees who attended the sessions on Wednesday is?

Correct Option: 3

According to the question:

\frac{\text{Monday + Tuesday + Wednesday}}{3}=32

\frac{\text{Wednesday + Thursday + Friday + Saturday}}{4}=30

\frac{\text{Monday + Tuesday + Wednesday + Thursday + Friday + Saturday}}{6}=26

\text{Monday + Tuesday + Wednesday = 96}

--> Eq. 1

\text{Wednesday + Thursday + Friday + Saturday = 120}

--> Eq. 2

\text{Monday + Tuesday + Wednesday + Thursday + Friday + Saturday}=156

--> Eq. 3

Add Eq. 1 and Eq. 2:

\text{Monday + Tuesday + 2(Wednesday) + Thursday + Friday + Saturday}=216

Subtract Eq. 3 from this, and we'll get:

\text{Wednesday}=216-156=60
