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

Dear Godemol,

You forgot to add the 150 & 725 of container A to your 7125 Ans.

7125 + 875= 8000

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...
