If an increase of 40% is made in the average number of female employees, working in countries III, IV and V, then their resulting average number will be what per cent of the average number of female employees ?

Country III :

Total employees = $$\frac{8}{100}$$ * 86000 = 6880

Female employees = 6880 - $$\frac{12}{100}$$ * 56000

= 6880 - 6720 = 160

Country IV :

Total employees = $$\frac{14}{100}$$ * 86000 = 12040

Female employees = 12040 - $$\frac{18}{100}$$ * 56000

= 12040 - 10080 = 1960

Country V :

Total employees = $$\frac{17}{100}$$ * 86000 = 14620

Female employees = 14620 - $$\frac{18}{100}$$ * 56000

= 14620 - 10080 = 4540

$$\therefore$$ Total female employees = 160 + 1960 + 4540 = 6660

Average = $$\frac{6660}{3}$$ = 2220

=> New average = $$\frac{140}{100}$$ * 2220 = 3108

Earlier average = $$\frac{86000 - 56000}{8}$$ = 3750

$$\therefore$$ Required % = $$\frac{3108}{3750}$$ * 100 = 83%
