question:
750 students took the test on English and Maths. 35% students failed in english and 45% failed in maths. 40% of those who passed in maths also passed in english, then how many students failed in both ? Choose the correct choice:
A) a) 162
B) b) 15
C) c) 60
D) d) 38
E) e) 12

chain:
Passed in english = 65%   Passed in maths = 55%   Passed in both = 40% of 55% = 2/5 * (55%) = 22%   Passed in (English + Maths - b) 15oth + Neither) 2/5 * (55 )=
