1970 women 2000 * 15/100 = 300 and executives 30
2012 5400 * 40 % = 2160
change 2160-30/30 = 7100 IMO C

Answer should be C not D. Please check.
\(\frac{40}{100}\) * \(\frac{45}{100}\) * 12000= 2160....in 2012
\(\frac{10}{100}\) * \(\frac{15}{100}\) * 2000 =30.....in 1970
\(\frac{(2160-30)}{30}\) * 100 = 7100
