Directions (Questions 91 - 95 ) : study the following table and answer the questions given below it.

Production of wheat by six major production units of India in Million Tonnes

PRODUCTION UNITS
MONTH	A	B	C	D	E	F
JANUARY	352	320	212	230	260	408
FEBRUARY	348	315	218	234	267	412
MARCH	336	318	205	232	254	420
APRIL	334	327	214	222	263	425
MAY	331	330	216	228	250	428

91.What was approximate percentage decrease in wheat production of unit A in May as compared to January?
a)4%
b)12%
c)8%
d)6%
e)10%

Ans.(d)6%
For unit A,  the production in May = 331
The production in January = 352
Decrease in percentage = (352 - 331)/352 * 100
                                      = 21/352 * 100
                                      = 5.97% ≈ 6%

 

92.which unit has a contribution of approximately 23% in the total sugar production in February?
a)B
b)A
c)F
d)D
e)E

Ans.(c)F
Total production in February = 348 + 315 + 218 + 234 + 267 + 412 = 1794
23% of total = 23/100 * 1794 = 412.62 ≈ 412

 

93.Which month has the largest production of wheat?
a)January
b)February
c)March
d)April
e)May

Ans.(b)February
Total production in January = 352 + 320 + 212 + 230 + 260 + 408 = 1782
Total production in February = 348 + 315 + 218 + 234 + 267 + 412 = 1794
Total production in March = 336 + 318 + 205 + 232 + 254 + 420 = 1765
Total production in April = 334 + 327 + 214 + 222 + 263 + 425 = 1785
Total production in May = 331 + 330 + 216 + 228 + 250 + 428 = 1783

 

94.Which of the following units shows continuous increase in production of sugar over months?
a)F
b)E
c)D
d)C
e)B

Ans.(a)F

 

95.What is the approximate percentage increase in total production from march to april?
a)2%
b)1%
c)3%
d)5%
e)4%

Ans.Total production in March = 336 + 318 + 205 + 232 + 254 + 420 = 1765
Total production in April = 334 + 327 + 214 + 222 + 263 + 425 = 1785 
Percentage increase = (1785 - 1765)/1765 * 100 = 1.13% ≈ 1%

 

Directions (Questions 96 - 100) : Study the following graph carefully and answer the questions given below it.

96.What was the percentage increase in price of commodity B from May to August ?
a)25.4%
b)43.5%
c)36.8%
d)37.5%
e)46.5%

Ans.(d)37.5%
Price of commodity B in May = 800
Price of commodity B in August = 1100 
Percentage increase = (1100 - 800)/800 * 100
                                 = 3/8 * 100 = 37.5%

97.What was the price difference between commodity A and B in the month of October?
a)Rs.500
b)Rs.300
c)Rs.700
d)Rs.400
e)Rs.600

Ans.(b)Rs.300
The price of commodity A in October = Rs.1200
The price of commodity B in October = Rs.900
Difference = 1200 - 900 = Rs.300

 

98.What was the approximate percentage decrease in the price of commodity A from May to August?
a)32%
b)17%
c)23%
d)35%
e)28%

Ans.(c)23%
Price of commodity A in May = 1100
Price of commodity A in August = 850
Percentage decrease = (1100 - 850)/1100 * 100
                                 = 250/1100 * 100
                                 = 22.72% ≈ 23%

 

99.In which of the following pairs of months was the price of commodity B same?
a)APRIL-JULY
b)MAY-AUGUST
c)JUNE-OCTOBER
d)MARCH-SEPTEMBER
e)AUGUST-SEPTEMBER

Ans.(d)MARCH-SEPTEMBER

 

100.What was the difference in average price between commodity A and B from May to September ?
a)Rs.50
b)Rs.20
c)Rs.70
d)Rs.40
e)Rs.60

Ans.(b)Rs.20
Average price of commodity A from May to September = (1100 + 1000 + 900 + 850 + 1150)/5 
                                                                                          = 1000
Average price of commodity B from May to September = (800 + 1000 + 1050 + 1100 + 950)/5
                                                                                          = 980
Difference = 1000 - 980 = Rs.20
