A½
[ 3.x.y/(2x*y) ]
9.A½
[ 3*L/[ (L/S1)+(L/S2)+(L/S3) ]
10.A½
4L/[ (L.S1)+(L/S2)+L/S3)+(L/S4) ]
11.A½
1/[ (x/100) * (1/S1) ] + [y/100) * (1/S2) ] + [ (z/100)*(1/S3) ]
kindly write the questions for the following as i am unable to under stand them
please give a brief description for formulae ..so that we can fetch more easily

please give a clear idea for these formulae
i think your 2nd formulae doesnt work
exmp
consider a classroom of 39 stu's of 15 yrs of age and if teacher weight is included avg is increased by 3 months find age of teacher
