| Misc. | 460 | 485 | 440 | 460 | 475 | 480 |
Q 1 - The quantity of sugar used in the month of April is approx. what percent of the total quantity of food items used in the same month?
A - 21%
B - 18%
C - 11%
D - 25%
Answer - C
Explanation
Quantity of sugar used in April = 210 Kg
Total quantity of food items used in april month = (260+290+210+245+375+460) kg
= 1860 kg
Required% = (210/1840*100)% = 11.4% ≅ 11%
Q 2 - What is the difference between the average quantity of rice used in all the given months together and the average quantity of wheat used in all months together?
A - 60 kg
B - 75 kg
C - 80 kg
D - 90 kg
Answer - D
Explanation
Average quantity of rice used = (250+230+210+260+240+220)/6 = 1410/6 = 235 kg
Average quantity of wheat used =(320+340+280+290+300+360) = 1890/6 = 315 kg
Required difference = (315-235)= 90 kg
Answer - D
Explanation
Average quantity of misc. items = (460+485+440+460+475+480)/6 =2800/6 = 466.67 kg
Answer - C
Explanation
Total quantity of pulses consumed =(360+300+320+245+235+250) =1710 kg
Total quantity of vegetable consumed = (380+390+385+375+355+370 )=2255Kg
Required difference = (2255-1710)= 545 kg
Answer - C
Explanation
total quantity of food items consumed in march =(210+280+200+245+375+460)=1835
total quantity of food items consumed in april =(260+290+210+245+375+460) =1840kg
required ratio = 1835: 1840 = 367:368
Directions(Q 6 to Q 10): Answer the questions given below using the table below:
Number of workers in the given six shifts of various factories.
| Shifts\factory | L | M | N | O | P |
|---|
| 7-11am | 7.5 | 8.0 | 7.8 | 7.59 | 8.32 |
| 11am-3pm | 6.38 | 7.0 | 7.16 | 6.5 | 7.5 |
| 3pm-7pm | 6.5 | 7.28 | 6.35 | 6.15 | 7.24 |
| 7pm-11pm | 7.8 | 5.25 | 6.0 | 6.0 | 6.5 |
| 11pm-3am | 5.5 | 5.0 | 5.10 | 5.5 | 5.7 |
| 3am-7am | 4.2 | 3.0 | 4.12 | 3.5 | 2.15 |
Q 6 - The total number of workers from factory O is approx. what % of the total number of workers from factory L?
A - 89%
B - 80%
C - 96%
D - 93%
Answer - D
Explanation
Total number of workers from factory O =(7.59+6.5+6.15+6+5.5+3.5)thousand
=(35.24*1000)= 35240
Total number of workers from factory L =(7.5+6.38+6.5+7.8+5.5+4.2)
=(37.88 *1000) =37880
∴ Required % =( 35240/ 37880* 100)% = 93.03%= 93%
Answer - C
Explanation
Average number of workers in factory P = (8.32+7.5+7.24+6.5+5.7+2.15)/6 *1000
=37410 /6 = 6235
Q 8 - What is the difference in the total number of workers in various shifts from factory M and the total number of workers in various shifts from factory O?
A - 290
B - 275
C - 295
D - 270
Answer - A
Explanation
Total number of workers in factory M =(8+7+7.28+5.25+5+3)*1000= (35.53*1000)
=35530
Total number of workers in factory O = 35240
Required difference =(35530- 35240 ) =290
Q 9 - What is the ratio of the total number of workers from factories L and M working in the shift of 11 p.m to 3 a.m and the total number of workers working in the same shift from factories O and P?
A - 13:14
B - 15:16
C - 13:15
D - none of these
Answer - B
Explanation
Number of workers in factories Land M in the shift of 11 p.m to 3.am. =(5.5+5)*1000 = (10.5*1000) = 10500.
Numbers of workers in factories O and P in the shift of 11 p.m to 3.am =(5.5+5.7)*1000 = (11.2*1000) =11200
Required ratio = 10500 : 11200 = 15 : 16
Q 10 - What is the total of the average number of workers working in the shift of 7 a.m to 11 a.m from all the factories and the average number of workers working in the shift of 7 p.m to 11p.m from all the factories?
A - 11502
B - 15142
C - 14520
D - 14152
Answer - D
Explanation
Average number of workers working in the shift of 7 a.m to 11a.m from all factories
=(7.5+8+7.8+7.59+8.32)*1000/5 = 39210/5 = 7842
Average number of workers working in the shift of 7 a.m to 11p.m from all factories
=(7.8+5.25+6+6+6.5)*1000 /5 = 31550/5 = 6310
Required total = 7842- 6310 = 14152
