Note: Total employees = total employees who worked from company GHL + total employees who worked from company PTU

Ques: If number of employees who worked in dept Z and A from company KCL are 35% and 20% more than that of from company GHL respectively, then what is the total number of employees who worked in dept Z and A together from company KCL?

Correct Answer: (a) 6975 
Solution:

Total number of employees who worked in five dept in all two companies = 25000

Number of employees who worked in dept X from both companies = 25000 × 16/100 = 4000

Number of employees who worked in dept X from company GHL = 4000 × 5/8 = 2500

So, number of employees who worked in dept X from company PTU = 4000 - 2500 = 1500

The number of employees who worked in dept Z and A from company KCL = 135/100 × 2500 + 120/100 × 3000 = 6975

92. What is the difference between the number of employees who worked in dept X and B from company PTU together and the number of employees who worked in dept Y and A from company GHL together?

Correct Answer: (b) 3250 
Solution:Required difference = (3000 + 3000) - (1500 + 1250) = 3250

93. If number of employees who worked in dept K and L from company PTU is 30% and 20% less than the number of employees who worked in dept X and A from company PTU, respectively then the number of employees who worked in dept K and L together from company PTU?

Correct Answer: (b) 2650 
Solution:The number of employees who worked in dept K and L from company PTU = 70/100 × 1500 + 80/100 × 2000 = 2650

94. The number of employees who worked in dept A and B together from company GHL is what percentage more or less than the number of employees who worked in dept X and Y together from company PTU?

Correct Answer: (b) 4.54% 
Solution:

The number of employees who worked in dept A and B together from company GHL = 3000 + 2250 = 5250

The number of employees who worked in dept X and Y together from company PTU = 1500 + 4000 = 5500

Required percentage = (5500 - 5250)/5500 × 100 = 4.54%

95. What is the ratio of number of employees who worked in dept Y and A from company PTU together to the number of employees who worked in dept Z and B from company GHL together?

Correct Answer: (d) 24 : 19 
Solution:Required ratio = (4000 + 2000) : (2500 + 2250)
= 24 : 19

96. Directions (96-99): Study the following information carefully and answer the questions given below:

The following bar graph represents total distance travelled (in Km) by five buses on two different days of a week.

The following table represents respective ratio of the distances travelled by the buses with high speed and low speed.

Buses

Monday (Distance travelled with High speed : Low speed)

Tuesday (Distance travelled with High speed : Low speed)

A

5 : 4

7 : 5

B

4 : 5

11 : 9

C

16 : 15

6 : 5

D

7 : 5

3 : 5

E

7 : 6

4 : 5

Ques:  Find the respective ratio of the sum of the distances travelled by bus A with high speed on Monday and Tuesday to sum of the distances travelled by bus C with low speed on Monday and Tuesday.

Correct Answer: (d) 6 : 5 
Solution:

Total distance travelled by bus A on Monday = 450 Km

Distance travelled by bus A on Monday with high speed = 5/9 × 450 = 250 Km

Distance travelled by bus A on Monday with low speed = 4/9 × 450 = 200 Km

Similarly, we can calculate for all the buses and for both the days, as in the following table:

Buses

A

5/9 × 450 = 250

4/9 × 450 = 200

7/12 × 600 = 350

5/12 × 600 = 250

B

4/9 × 540 = 240

5/9 × 540 = 300

11/20 × 400 = 220

9/20 × 400 = 180

C

16/31 × 620 = 320

15/31 × 620 = 300

6/11 × 440 = 240

5/11 × 440 = 200

D

7/12 × 480 = 280

5/12 × 480 = 200

3/8 × 560 = 210

5/8 × 560 = 350

E

7/13 × 520 = 280

6/13 × 520 = 240

4/9 × 540 = 240

5/9 × 540 = 300

96. (d): Distance travelled by bus A with high speed on Monday = 250 Km
Distance travelled by bus A with high speed on Tuesday = 350 Km

Distance travelled by bus C with low speed on Monday = 300 Km
Distance travelled by bus C with low speed on Tuesday = 200 Km

Required ratio = (250 + 350) : (300 + 200)
= 600 : 500 = 6 : 5

97. Total distance travelled by all the buses on Monday is approximately what percent of the total distance travelled by all the buses on Tuesday?

Correct Answer: (e) 103%
Solution:

Total distance travelled by all the buses on Monday
= 450 + 540 + 620 + 480 + 520 = 2610 Km

Total distance travelled by all the buses on Tuesday
= 600 + 400 + 440 + 560 + 540 = 2540 Km

Required percentage = 2610/2540 × 100
= 102.75% = 103% approx.

98. Find the difference between total distance travelled by bus B and bus D with high speed on Monday and total distance travelled by bus C and bus E with high speed on Tuesday.

Correct Answer: (a) 40 Km 
Solution:

Distance travelled by bus B with high speed on Monday = 240 Km
Distance travelled by bus D with high speed on Monday = 280 Km
Total distance travelled by bus B and bus D with high speed on Monday = 240 + 280 = 520 Km

Distance travelled by bus C with high speed on Tuesday = 240 Km
Distance travelled by bus E with high speed on Tuesday = 240 Km
Total distance travelled by bus C and bus E with high speed on Tuesday = 240 + 240 = 480 Km

Required difference = 520 - 480 = 40 Km

99. Find the average of the low speed distance travelled by all the buses on Monday.

Correct Answer: (c) 248 Km 
Solution:

Low speed distance travelled by bus A on Monday = 200 Km
Low speed distance travelled by bus B on Monday = 300 Km
Low speed distance travelled by bus C on Monday = 300 Km
Low speed distance travelled by bus D on Monday = 200 Km
Low speed distance travelled by bus E on Monday = 240 Km

Required average = (200 + 300 + 300 + 200 + 240)/5 = 1240/5 = 248 Km

The number of males who watch Spanish TV series from city U and V together = 5000 + 5600 = 10600

The number of females who watch English TV series from city W and Y together = 2100 + 3600 = 5700

Required % = 10600/5700 × 100 = 185.96% ≈ 186% (approx.)
