Answer 1

Answer:

Rs.488.75

Step-by-step explanation:

Let us take the salary of four members as a,b,c and d.

Average$\frac{a+b+c+d}{4}$ =610.25

From this, a+b+c+d=2441                ......(i)

Now, one member is left out...

$\frac{a+b+c}{3}$=650.75

a+b+c=1952.25

From (i), a+b+c+d=2441

d=2441-1952.25

d=488.75

The salary of the left one is Rs.488.75
