Question "The average of 11 results is 50. If the average of first 6 result is 49 and that of last 6 results is52. Find the sixth result." should be "The average of 11 numbers is 50. If the average of the first 6 numbers is 49 and that of the last 6 numbers is 52. Find the value of the sixth number"
Also in explanation there is a wrong equation, it says:
50 = 294+312-x/11
and it should be:
50 = (294 + 312 - x) / 11
and the answer is x = 56

Question "A Batman die scored an average of 12 runs in 7 innings in a cricket match. He played over more inning and the average then became 14. The rings he scored in the last innings are" there is an error in the explanation. It says:
14=84+x/28=28
and it should be:
14 = (84 +x) / 8
and the answer is x = 28

Question "The average weight of A,B & C is 48 kg. If the average weight of A and B be 45 kg and that of B and C be 50 kg. Find weight of B." there is an error in the explanation. It says:
48=x+y+z/3
45=x+y/2
50=y+z/2
and it should be:
48 = (x + y + z) / 3
45 = (x + y) / 2
50 = (y + z) / 2

Question "The average weight of 5 persons is decreased by 2 kg when one of the men whose weight is 50 kg is replaced by a new man. The weight of the new man is?" there is an error in the explanation and it's unclear how the solution comes.
Solution:
Let the average weight of the five persons be x, the weight of the man removed be r and the weight of the new man be n. Then:
Total weight of the first five persons: 5x
Total weight of the last five persons: 5x - r + n
Then: (5x - r + n) / 5 = x - 2
Then: 5x - r + n = 5x - 10
Then: n = r - 10 = 50 - 10 = 40

Question "12 yr ago, the average age of a husband and a wife was 20 yr. The average remains the same today, when they have two children. What is the present age of the youngest child, if they differ in age by 2 yr." there is an error in the explanation. It says:
20=64+x+x+2/4
and it should be:
20 = (64 + x + x + 2) / 4
and the answer is x = 7

Question "The average income of 20 employees in an oftice is 1800 per month. If one more employee is added the average salary becomes 1810 per month. What is the monthly salary of the new employee?" has a typo in the question description and an error in explanation. It says "oftice" instead of "office" and in explanation it says:
1810=36000+x/21
and it should be:
1810 = (36000 + x) / 21

Question "The average of 5 quantities is 6. The average of three of them is 4.
What is the average of remaining two quantities?" there is an error in the explanation. It says:
3 x 4 x 2 x y/5 =6
and it should be:
(3 x 4 + 2 x y) / 5 = 6
and the answer is y = 9

Question "Find the average of all the numbers between 6 and 34 which are divisible by 5." there is an error in explanation. It says:
(10+15+20+25+30/5)=100/5=20
and it should be:
(10+15+20+25+30)/5=100/5=20

Question "The average of the first five multiples of 3 is" there is an error in explanation. It says:
Average=3(1+2+3+4+5/5)=45/5=9
and should be:
Average=3(1+2+3+4+5)/5=45/5=9

Question "The average weight of 16 boys in a class is 50.25 kg and that of remaining 8 boys is 45. 15 kgs. Find the average weight of all the boys in the class." there is an error in explanation. It says:
Required average = (50.25×16 + 45.15×8/16+8)
and should be:
Required average = (50.25×16 + 45.15×8)/(16+8)

I suggest to check all explanations and check the placement of parentheses. I stopped doing the quiz.
