1) How many have VCD and Ovens?

70% + 75% - 100% = 45%

2) How many have VCD, Ovens and ACs?

45% +80% - 100% = 25%

3) How many have all 4?

25% +85% - 100% = 10%

That's the answer

v 70%
o 75%
a 80%
w 85%

min employees having o+v = 70-25 = 45 (for min case, assuming that 25 of those who don't possess 'o' possess 'v')

min employees having a+w = 80-15 = 65
min employees having all four = 45-35 = 10
