Question

please please please give the answer of the following question because it's urgent as tomorrow is our board exams of mathematics so please give the answer​

Answer 1

first we take the total frequency that is 50

so we get 32+f1+f2=50

>f1+f2=18______this is 1

mean is given as 57.6

so we calculate the mean using sigma{fixi}/sigma{fi}

so we get a 1800+30f1+70f2/50=57.6

>1940+30f1+70f2=2880

>30f1+70f2=940

from 1> 30f1+70(18-f1)=940

>940=30f1-70f1+1260

>940-1260=-40f1

>-320=-40f1

>f1=320/40

therefore,f1=8

therefore,f1=8 in 1>8+f2=18

f2=18-8

f2=10
