Then,

The number of people out of 100 who had attended the previous year is;

\(\rm \dfrac{Number \ of \ people \ at \ festival}{Number \ of \ people \ attend \ festival}= \dfrac{ People\ out \of\ 100 \ had\ attended \ festival}{x}\\\\\dfrac{600}{420}}=\dfrac{100}{x}\\\\x \times 600 = 420 \times 100\\\\600x = 42000\\\\x = \dfrac{42000}{600}\\\\x = 70\)
