12 degrees
20 degrees
13 degrees

cannot be determined
Explanation
Answer – CExplanation:
Sum of temperature for Sunday, Monday and Tuesday = 55 * 3 = 165 degrees
Sum of temperature for Monday, Tuesday and Wednesday = 70 * 3 = 210 degrees
Since temperature on Wednesday = 58 degrees
Temperature for Monday and Tuesday = 210 –58 = 152 degrees
Temperature of Sunday = 165 – 152 = 13 degrees.

A cricketer whose bowling average is 12.4 runs per wicket takes 4 wickets for 26 runs and thereby decreases his average by 0.4. The number of wickets taken by him till the last match was:
55
65
75
87
none of these
Explanation
Answer – AExplanation:
Let the number of wickets taken till the last match be x.
Then, (12.4x + 26)/x+4 = 12 => 12.4x + 26 = 12x + 48
=> 0.4x = 22 => x = 22/0.4 = 220/4 = 55.

The average mark of a class of m students is 64. When eight new students with an average mark of 73 join the class, the new average of the entire class is a whole number. Find the number of students now in the class, given that m lies between 25 and 60.
36
28
54
72
84
Explanation
Answer – AExplanation:
Let x be the increase in the average
=> x = (73 – 64)8/m+8 => x = 9*8/m+8
For m to be a whole number 72 (=9*8) should be divisible by (m+8)
From the choices it can be said that 36 and 72 are two such factors. But 72 does not lie within the range.
So, m+8 = 36

Question no.6
The captain of a football team of 11 members is 26 years old and the goal keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. Find the average age of the team.
23 years
26 years
46 years
50 years
None of these
Explanation
Answer – AExplanation:
Number of members in the team = 11
Let the average age of the team = x
=> (Sum of the ages of all the 11 members of the team)/ (11) = x
=> Sum of the ages of all the 11 members of the team = 11x
Age of the captain = 26
Age of the goalkeeper = 26 + 3 = 29
Sum of the ages of 9 members of the team excluding captain and goal keeper
= 11x – 26 – 29 = 11x – 55
Average age of 9 members of the team excluding captain and goalkeeper = (11x – 55)/9
Given that (11x – 55)/9 = (x-1)
=> 11x – 55 = 9(x-1)
=> x=46/2 = 23 years

Question no.7
Average of five numbers is 61. If the average of first and third number is 69 and the average of second and fourth number is 69, what is the fifth number?
31
29
25
35
none of these
Explanation
Answer - BExplanation:
Let the five numbers be x1, x2, x3, x4, x5,
Average of 5 numbers = 61
(x1 + x2 + x3 + x4 + x5)/5 = 61
x1 + x2 + x3 + x4 + x5 = 305
Now, (x1 + x3)/2 = 69
x1 + x3 = 138
(x2 + x4)/2 = 69
x2 + x4 = 138
Now, x1 + x2 + x3 + x4 + x5 = 305
138 + 138 + x5 = 305
x5 = 305 – 276 = 29

Average weight of 19 women is 74 kgs, and the average weight of 38 men is 63 kgs. What is the average weight (rounded off to the nearest integer) of all the women and the men together?
59 kg
65 kg
69 kg
67 kg
60 kg
Explanation
Answer – DExplanation:
Average weight of 19 women = 74 kg
Total weight of 19 women = 74 * 19 = 1406 Kg
Average weight of 38 men = 63
Total weight of 38 men = 38 * 63 = 2394
Average weight of women and men together = (1406 + 2394)/ (19 + 38) = 3800 / 57 = 66.67 ~ 67 kg

Question no.9
A firm of readymade garments makes both men’s and women’s shirts. Its average profit is 6% of the sales. Average profit in women’s shirts is 8% of the sales and men’s shirts comprise 60% of the output. The average profit per sale rupee in men shirts is
none of these
0.0446
0.0166
0.0666
0.0466
Explanation
Answer - EExplanation:
Men’s shirt compromise 60% of the output.
Women’s shirts comprise (100-60) = 40% of the output.
Average profit from women’s shirt = 8% of 40 = 3.2 out of 40
Overall average profit = 6 out of 100
Average profit from men’s shirts = 2.8 out of 60 i.e., 0.0466 out of each shirt.

Question no.11
There are only five people in the Arman Thakkar’s family. Arman, his wife, a son and two daughters. The younger daughter’s age is 4/5th of the elder daughter’s age. The age of eldest daughter is 3/8 times that of her father Arman and the age of the son is 1/5th that of his father Arman. 4 years ago the age of her wife was 8 times that of his son and now the sum of the ages of the younger daughter and wife is same as the sum of the ages of Arman and his son. The average age of the family is:
22.20 years
22.40 years
21.22 years
21.44 years
none of these
Explanation
Answer – A
Explanation:
Arman Wife Son Elder Daughter Younger Daughter
5x < -------> x 5z 4z
8y < ----------------------------> 3y
=> 40K W 8K 15k 12K
Again, since Younger Daughter + Wife = Arman + Son (K = x*y)
=> 12K + W = 40 K + 8 KW -----> age of wife
=> W = 36 K
Thus 4 years ago
(36K-4) = 8(8K-4)
=> 28K = 28 => K=1
Therefore, the age of Arman = 40
Wife = 36
Son = 8
Elder Daughter = 15
Younger Daughter = 12
Hence, the average age of the family = 111/5 = 22.20 years.
