Q:23 answer:
"For every household that used both brands of soap, 3 used only Brand B soap" means that if x used both A and B, then 3x used only B (but not A). So, --> 4x + 140 = 200 --> x= 15
Q:22 answer:
Total = Set1 + Set2 + Set3 + Neither - Both - (All three X 2)
200 = 112 + 88 + 80 + 0 – (60+X) - 0*2
X = 20
This is the additional number of people who like both.
80 – 20 = 60
People who like only strawberry minus the people who like strawberry and something else.
The answer is (B) 60..
Q:21 answer:
Assume 'x' number of persons received medals in exactly two of these categories
Number of persons that received medals in exactly one of these categories= 45-x-4 = 41-x
41-x + 2*x + 3*4 = 36+18+12= 66
x = 13
all the options are wrong answer: 13
