1. Kishore can do a piece of work in 9 days, and Chaitanya can do the same work in 18 days. They started the work. After 3 days, Eswar joined them, who can complete the same work in 3 days. What is the total number of days in which they completed the work?
A. 4 days
B. 6 days
C. 8 days
D. 12 days
Answer – A. 4 days
Explanation:
Efficiency of Kishore and Chaitanya = 11.11 + 5.55 = 16.66%
Work done in 3 days = 3 x 16.66 = 50%
The rest work was done by Kishore, Chaitanya & Eswar = 50/50 = 1 day
Therefore, the Work can be completed in 4 days.
2. The average mark of the students of a class in a particular exam is 80. If 5 students whose average mark in that exam is 40 are excluded, the average mark of the remaining will be 90. Find the number of students who wrote the exam.
A. 15
B. 20
C. 25
D. 30
Answer – C. 25
Explanation:
Let the number of students who wrote the exam be x.
Total marks of students = 80 x.
Total marks of (x – 5) students = 90(x – 5)
80x – (5 * 40) = 90(x – 5)
250 = 10x => x = 25
Therefore, the Number of students who wrote an exam is 25.
3. Two pipes, P and Q, can fill a tank in 20 and 30 minutes, respectively. If both pipes are used together, then how long will it take to fill the tank?
A. 12 min
B. 15 min
C. 25 min
D. 50 min
Answer – A. 12 min
Explanation:
According to the given information
Part filled by P, in 1 min. = 1/20
Part filled by Q in 1 min. = 1/30
Then, Part filled by (P + Q) in 1 min. = 1/20 + 1/30 = 1/12.
Hence, both pipes can fill the tank in 12 minutes.
4. One pipe can fill a tank three times as fast as another pipe. If together the two pipes can fill a tank in 36 min, then the slower pipe alone will be able to fill the tank in?
A. 81 min
B. 108 min
C. 144 min
D. 192 min
Answer – C. 144 min
Explanation:
Let us assume the slower pipe alone fills the tank in x minutes.
Then, a faster pipe will fill it in x/3 min.
So, 1/x + 3/x = 1/36
4/x = 1/36 => x = 144 min.
5. In an office, there are 40% female employees. 50% of male employees are UG graduates. A total of 52% of employees are UG graduates out of 1800 employees. What is the number of female employees who are UG graduates?

B. 396
C. 412
D. 428
Answer – B. 396
Explanation:
Given that
Total employees = 1800
female employees = 40%
male employees = 60%
50% of male employees = UG graduates = 30%
Female employees who are UG graduates = 22%
22% of 1800 = 396
6. In an examination, Srikanth scored 56% marks, Manas scored 90% marks, and Eswar scored 650 marks that are 65% Find the total marks of the three students?

B. 2010
C. 2110
D. 2450
Answer – C. 2110
Explanation:
65% = 650
100% = 100*650/65 = 1000
56% = 560
90% = 900
Total = 650+560+900 = 2110
Therefore, the Total marks scored by three students are 2110.
7. X and Y invested rupees 4000 and 5000, respectively, in a business. X, being an active partner, will get rupee 50 every month for running the business. In a year, if X receives a total of 800 rupees, then what will Y get from the business?

X = 2300
R = 7*2300 = 16100
S = 9*2300 = 20700
R+S = 36800
Therefore, the Total amount of R and S together is Rs. 36800.

A. 35 cm
B. 42 cm
C. 45 cm
D. 56 cm
Answer – D. 56 cm
Explanation:
Circumference = 2*(22/7)*49 = 308 cm
length of rectangle sides is 4x, 7x.
Circumference = 2*(4x+7x)
308 = 22x
x= 308/22 = 14
Hence, the smaller side of the rectangle = 4x= 4*14=56 cm
10. The perimeter of a square is twice the perimeter of a rectangle. If the perimeter of a square is 48 cm and the length of the rectangle is 7cm. Find the breadth of the rectangle?

P of Square = 4a = 48
a = 48/4 = 12 cm
P of rectangle = 48/2 = 24 cm =2(l+b)
2(7+b) = 24
b = 12-7 = 5
Hence, the breadth of the rectangle is 5 cm.
