Let people that did not join any class = x
For Overlapping Sets:
Total= Group 1 + Group 2 + Group 3 - (Sum of 2 Group Overlaps) -(2* All Three) + Neither
=> 100 = 23+22+34 - 12-6+x
=> 39% - Ans.

As per Formula:
(Mean% - % of Lower Concentration) / (% of Higher Concentration-Mean)= (Ratio of qty of Lower Conc [x] / (Ratio of qty of Higher Conc [y]
=> (35%-25%)/(40%-35%) = x/y
=> 10/5 = x/y
=> x+y =15
Therfore, Quantity of Higher conc. replaced = (x/x+y)=5/15=1/3
Ans 1/3

The probability of having a girl in all 3 cases is :
=> 1/2*1/2*1/2= 1/8
The probability of NOT having a boy in all 3 cases is :
=> 1/2*1/2*1/2= 1/8
Therefore the probability of having a girl and not a boy will be;
=> 1/8 +1/8
=> 2/8
=> 1/4
Ans : 1/4

Since BE is ll to CD that makes triangle ABE and triangle ACD similar triangles. Hence AB/AC = AE / AD = BE / CD now we can get AB=3, AE = 4, BE=5 AC= 6, CD = 10, AD = 8. Area of triangle ABE = sqrt(s*(s-a)*(s-b)*(s-c)) Where s=(a+b+c)/2. Solving this we will get Area of ABE= sqrt 36 = 6 Area of ACD...
