Rs. 48000

If the annual incomes of Mukesh, Anil and Ratan are M , A and R respectively, then
Given, (M+A)/2 =3800, M + A= 7600 ---(i)
(A+R)/2 =4800, A + R= 9600 ---(ii) &
(R+M)/2 = 5800, R + M= 11600 ---(iii)
On solving (i), (ii) & (iii), M=4800, A=2800 & R=6800
So arithmetic mean of incomes of the three =(4800+2800+6800)/3 =4800
