Directions: A function is to be organised in an auditorium. There is a gate in the auditorium having dimensions 4 feet × 7 feet. The auditorium has 100 chairs, 25 tables, 2 podiums and 5 sound boxes. The dimensions of these objects are given in the table below. Now, on the basis of the given information, answer the question that follows. Sr. No. Object Length Breadth Height 1. Auditorium 50 feet 40 feet 10 feet 2. Chair 2 feet 3 feet 3 feet 3. Table 4 feet 4 feet 5 feet 4. Podium 3 feet 4 feet 4 feet 5. Sound box 2 feet 2 feet 2 feet

What percent area of the floor is covered by the tables if they are placed side by side?

  1. 30%

  2. 20%

  3. 15%

  4. 8%

  5. 12%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Total floor area = 50 * 40 = 2000 sq ft. Each table is 4 * 4 = 16 sq ft. 25 tables = 25 * 16 = 400 sq ft. Percent area = (400 / 2000) * 100 = 20%.

Passage

Total number of phones received for repairing by the service centers of different companies viz. A , B , C and D , from different regions viz. M , N , O , P , R and S : COMPANY/REGION M N O P R S A 560 450 460 200 280 300 B 460 350 650 390 120 600 C 402 455 350 580 300 400 D 660 680 500 390 390 360

If a pie chart is made with the number of phones received by companies A, B, C and D from regions M, N, O and P, what will be the measure of the central angle corresponding to the number of phones received by companies A, B, C and D from region O?

  1. 86.4°

  2. 90°

  3. 93.6°

  4. 97.2°

  5. 100.8°
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Total phones from region O: 460 (A) + 650 (B) + 350 (C) + 500 (D) = 1960. Total phones from M, N, O, P: (560+450+460+200) + (460+350+650+390) + (402+455+350+580) + (660+680+500+390) = 1670 + 1850 + 1787 + 2230 = 7537. The calculation requires summing the specific subset.

Passage

Directions : The pie chart below shows the percentage distribution of total employees in four departments. The table below shows the number of contractual employees in each department. A company has 5,000 employees, including both permanent and contractual employees, working in four different departments: HR, IT, Sales, and Finance. Read the following pie chart and table carefully and answer the question given below. Department Contractual employees HR 40% of total employees in Sales IT --- Sales 300 Finance --- The average number of contractual employees in HR, IT, and Finance is 400. The ratio of contractual employees in Finance to IT is 3 : 5.

If 30% employees from each department are moved to a newly created Operations department, find the central angle representing Operations in a new pie chart.

  1. 60°

  2. 72°

  3. 90°

  4. 108°

  5. 120°

Passage

Directions: Refer to the data given below. The first set of data gives information about the number of units of different products sold by store from 2001 to 2004 and the second set of data gives information about the profit earned per unit of product from 2001 to 2004. Units of Products Sold Year P Q R S 2001 253 359 450 500 2002 150 320 220 300 2003 180 320 150 520 2004 200 660 500 505 Profit per unit of product (in Rupees) Year P Q R S 2001 30 35 40 50 2002 50 80 40 60 2003 40 30 80 40 2004 50 40 50 80

If the profit of store from product S from 2001 to 2004 is represented in the form of pie chart, then what is the central angle corresponding to profit of store from product S in 2003?

  1. 67.85°

  2. 69.25°

  3. 71.86°

  4. 72.46°

  5. 74.86°
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Profit from S: 2001 (500*50=25000), 2002 (300*60=18000), 2003 (520*40=20800), 2004 (505*80=40400). Total profit = 25000+18000+20800+40400 = 104200. Angle for 2003 = (20800 / 104200) * 360 = 0.1996 * 360 = 71.86 degrees.

Directions: Study the table and answer the question that follows. The given table shows the number of seats reserved in different classes in a train on six days of a week. The number of seats available in each class is given in brackets. Day 2 nd Class Non-AC (900) 1 st Class Non-AC (400) AC III Tier (500) AC II Tier (300) AC 1 st Class (120) Monday 690 240 340 195 70 Tuesday 720 250 410 240 90 Wednesday 840 280 360 175 85 Thursday 800 360 420 160 95 Friday 750 275 350 170 100 Saturday 760 320 380 230 108

If the data related to vacant seats for AC II Tier on the given six days is represented by a pie chart, then what is the difference (in degrees) between the central angles of the sectors representing vacant seats in these classes on Thursday and Monday?

  1. 18°

  2. 25°

  3. 24°

  4. 20°
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The AC II Tier vacant seats are: Monday (300-195=105), Tuesday (300-240=60), Wednesday (300-175=125), Thursday (300-160=140), Friday (300-170=130), Saturday (300-230=70). Total vacant seats = 105+60+125+140+130+70 = 630. Angle per seat = 360/630 = 4/7 degrees. Difference between Thursday (140) and Monday (105) is 35 seats. Difference in angle = 35 * (4/7) = 20 degrees.
