The average expenditure of the hotel when there are 10 guests is Rs. 80 per guests and the average expenditure is Rs.40 when there are 30 Guests. If it is known that there are some fixed expenses irrespective of the number of guests then the average expenditure per guest when there are 50 guests in the hotel.?

A.
Rs. 25
B.
Rs. 32
C.
Rs. 50
D.
Rs. 45
E.
None of these

Detailed Solution for Test: Ages - 3 - Question 3

Let the fixed expenditure of the hotel be Rs.x and the variable expenditure is Rs.y , then
x + 10y = 800 ---------(1)
x + 30y = 1200 ----------(2)
20y = 400
y = Rs. 20 and x= 600
Hence the total expenditure when there are 50 guests = 600 + 50 x 20

= 1600
Average expenditure = 1600 /50

= Rs. 32

Test: Ages - 3 - Question 4

Save

The average marks of Sumit decreased by one, when he replaced the subject in which he has scored 40 marks by the other two subjects in which he has just scored 23 and 25 marks respectively. Later he has also included 57 marks of Computer Science, then the average marks increased by two. How many subjects were there initially?

A.
12
B.
14
C.
10
D.
15
E.
13

Detailed Solution for Test: Ages - 3 - Question 4

Total subjects = x ; Average Marks = y
(x + 1)(y – 1) = (xy – 40) + (23 + 25)
y – x = 9 –(1)
(x + 2)(y + 1) = (xy – 40) + (23 + 25)+ 57
xy + 2y + x + 2 = xy + 65
2y + x = 63 –(2)
From Equation (1) and (2) ⇒ x = 15; y = 24

Test: Ages - 3 - Question 5

Save

The average runs scored by a cricketer is 42 innings, is 40. The difference between his maximum and minimum scores in an inning is 100. If these two innings are not taken into consideration, then the average score of remaining 40 inning is 38. Calculate the maximum runs scored by him in an innings ?

A.
125
B.
130
C.
110
D.
100
E.
None of these

Detailed Solution for Test: Ages - 3 - Question 5

Let the minimum score = x
∴ Maximum score = x + 100
∴ x + (x + 100) = 40 x 42 – 40 x 38
⇒ 2x + 100 = 1680 – 1520 = 160
⇒ 2x = 160 – 100 = 60
⇒ x = 30
Maximum score = x + 100 = 30 + 100 = 130

The average weight of 4 persons, Amit, Bala, Catherine and David is 65 kg. The 5th person Elina is included and the average weight decreses by 2 kg. Amit is replaced by Francis. The weight of Francis is 4 kg more than Elina. Average weight decreases because of the replacement of Amit and now the average weight is 64 kg. Find the weight of Amit.

A.
54 kg
B.
66 kg
C.
55 kg
D.
68 kg
E.
None of these

Detailed Solution for Test: Ages - 3 - Question 6

Sum of the weight of Amit, Bala, Catherine and David = 65 x 4 = 260 kg
Average weight of Amit, Bala, Catherine and David = 65 – 2 = 63kg
Sum of the weight of Amit, Bala, Catherine and David and Elina = 63 x 5 = 315 kg
Weight of Elina = 315 – 260 = 55 kg
Weight of Francis = 55 + 4 = 59 kg
Average weight of Francis, Bala, Catherine, David and Elina = 64 kg
Sum of the weight of Francis, Bala, Catherine, David and Elina = 64 x 5 = 320 Kg
Sum of the weights of Bala, Catherine, David = 320 – 55 – 59 = 206 kg
Weight of Amit = 260 – 206 = 54 kg

A.
12 : 7
B.
4 : 3
C.
2 : 3
D.
8 : 5
E.
None of these

Detailed Solution for Test: Ages - 3 - Question 7

Average weight of students of sections of Red and Black = 48 kg
⇒ (45a + 50b)/(a + b) = 48
⇒ 15a = 10b
Average weight of students of sections of Black and Green = 60 kg
⇒ 50b + 72c = 60(b + c)
⇒ 10b = 12c
Average weight of students of Red, Black, Green and Yellow = 60 kg
45a + 50b + 72c + 80d = 60(a + b + c + d)
⇒ 15a + 10b – 12c – 20d = 0
⇒ 15a = 20d
⇒ a : d = 4 : 3

Out of the three annual examinations, each with a total of 500 marks, a student secured average marks of 45% and 55% in the first and second annual examinations. To have an overall average of 60%, how many marks does the student need to secure in the third annual examination ?

A.
450
B.
400
C.
350
D.
300
E.
None of the Above

Detailed Solution for Test: Ages - 3 - Question 8

Total marks for three examinations = 3x 500 = 1500
Total required marks in three examinations = 60% of 1500
= (3 x 500 x 60) / 100
= 900
Marks secured in first examination = 45 % of 500
= (500 x 45) / 100
= 225
Marks secured in third examination = 55 % of 500
= (500 x 55) / 100
= 275
Thus, the required marks in third examination
= 900 – (225 + 275)
= 900 – 500
= 400

The average age of women and child workers in a factory was 20 year. The average age of all the 12 children was 8 year and average age of women workers was 26 year. If 9 women workers were married, then the number of unmarried women workers was.

A.
16
B.
17
C.

Detailed Solution for Test: Ages - 3 - Question 9

Women workers = x
26x + 12 x 8 = 20 (12+x)
⇒ 26x + 96 = 240 + 20x
⇒ 6x = 144
∴ x = 24
∴ Unmarried women workers = 24 – 9 = 15

⇒ 5y = 50
∴ y = 10
