In a group of 15 people, 8 read English, 7 read French while 3 of them read none of these two. How many of them read French and English both?	Choose the most appropriate option.
A) 2	B) 3	C) 4	D) 7	E) 5
In the following Venn diagram, F and E represent people who read French and English respectively.   Now, [F+({F ∩ E}) + E] = 15-3 (or) F+E+(F ∩ E) = 12 ......(1) Also, F+(F ∩ E) = 7; E+(F ∩ E) = 8. By adding, F+E+2(F ∩ E) = 15 ---------- (2) By subtracting (1) from (2), we get (F ∩ E) = 3. ∴ 3 of them read both French and English.   Answer:3
