Answer

Explanation

New number of female employees :
Country II
Total employees =6880
Female employees =6880-6720=160
Country IV
Total employees =12040
Female employees =12040-10080=1960
Country V
Total employees =14620
Female employees
`rArr 14620-10080=4540`
Total female employees
`160+1960+4540`
=6660
Average `=(6660)/(3)2220`
New average `=(2220xx140)/(100)=3108`
Earlier average
`=(86000-56000)/(8)=(30000)/(8)=3750`
`:.` Required percentage
`=(3108)/(3705)xx100=83%`
