Directions(Q 1 to Q 5): Answer the questions given below using the table below:

Quantity of various food items used by a restaurant during the first half of a year (in Kg.)

Food item	Jan	Feb	March	April	May	June
Rice	250	230	210	260	240	220
Wheat	320	340	280	290	300	360
Sugar	240	210	200	210	160	150
Pulses	360	300	320	245	235	250
Vegetable	380	390	385	375	355	370
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?

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?

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

Q 3 - What is the average quantity of miscellaneous items used in all the given month together?

Answer - D

Explanation

Average quantity of misc. items = (460+485+440+460+475+480)/6 =2800/6 = 466.67 kg

Q 4 - What is the difference between the total quantity of pulse and the total quantity of vegetables used during the given months?

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

Q 5 - What is the respective ratio of total quantity of food items used in the month of March to the total quantity of food items used in the month of April?

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?

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%

Q 7 - What is the average number of workers working in various shifts from factory P?

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?

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?

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?

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
