Assume total as 100
50 - speak french
56 - speak spanish
14 - 25% of Spanish speaking speak French ( 25X56/100= 14)
so FRENCH + SPANISH - FRENCH&SPANISH + NEITHER = 100
50+56-14+NEITHER = 100
NEITHER = 8
50 - speak french
56 - speak spanish
14 - 25% of Spanish speaking speak French ( 25X56/100= 14)
so FRENCH + SPANISH - FRENCH&SPANISH + NEITHER = 100
50+56-14+NEITHER = 100
NEITHER = 8
