A man wills 25% of his wealth to charity and rest to his family. What percent of the wealth willed to charity does the family get?

Let the total wealth of man be a

Amount of wealth to charity = a(25/100) = 0.25a

Amount of wealth to family = a(1 – 25/100) = 0.75a

∴ Required % = 100 + [(0.75a – 0.25a)/0.25a] × 100 = 300
