sandesh   10 years AGO

let take a+b+c+d/4=2940
then a+b+c+d=2940*4=11760-----eq(1)
then one man died so take a+b+c/3=2600
a+b+c=2600*3=7800----eq(2)
solve eq1 and eq 2 then we get d=3960 is the answer option 9

Jagruti   10 years AGO

Let total income of 4 members = x
Average of 4 members = 2940
therefore,x/4=2960
x=4*2940
x=11760

let y be the income of 4th member that died.
new average = 2600
therefore,(11760-y)/3 = 2600
therefore,y=3960
