Assume ------>>>>>>a month contains 4 weeks
------->>>>>First teacher be x
-------->>>>>second teacher be y
--------->>>>>Third teacher be z


Average salary of three teachers is x+y+z=6400
----------
3

then x+y+z = 6400*3 = 19200 per week
As mentioned in the above a month contains 4 weeks then 19200*4 = 76800

if x = 22500
y = 28000
then z= 76800 - (22500+28000) = 26300
Third teacher salary z = 23600

A)26300
First we have to calculate monthly avg incme of 3 teachers which is= (6400×4)=25600
Now total sal of two teachers= (22500+28000)
Sal of 3rd teacher=(76800-50500)=26300

for 1 week 6400 Rs.
so for 4 week it is = 4*6400 = 25600
avg= (22500+28000+x)/3
3*25600= 50500+X
therefore, x=76800-50500=26300.
