Direction (1-5) - Sales of mobile phone in the year 2005 and 2006 by the six branches A, B, C, D, E and F. Study the graph and answer the following questions.
Find the ratio of total sales of B in both years to the total sales of branch D in both years.
Explanation :
B = 75+65 = 140
D =85+95 = 180
B:D = 140:180 = 7:9
What is the average number of mobile phones sold in 2005 ?
Average = (80+75+95+85+75+70)/6 = 80
Which branch sold the maximum number of mobile phones in both years ?
A = 80 + 105 = 185
B = 75 + 65 = 140
C = 95 + 110 =205
D = 85 + 95 =180
E = 75 + 95 =170
F = 70 + 80 =150
What is the difference between the number of mobile phones sold in 2005 by branch A and 2006 by branch D ?
2005, A = 80
2006, D = 95
Diff = 95 – 80 = 15
Direction (6-10)- Study the graph and answer the following questions. Data related to the number of plants planted by 2 villages X and Y.
2001 2002 2003 2004 2005 2006 32 42 36 44 52 96 X 18 28 42 56 64 80 Y
Number of plants planted by village X increased by what percentage from 2001 to 2005 ?
% = [(52 -32)/32]×100 = 62.5%
What is the average number of plants planted by village Y during 2001,2003,2005 and 2006 ?
Avg = (18+42+64+80)/4 = 204/4 =51
What was the total number of plants planted by village Y in 2002 and 2006 ?
Y total = 28+80 = 108
Find the ratio of total number of plants planted by X in 2001 and 2002 to the total number of plants planted by Y in 2003 and 2004 ?
X 2001,2002 =32+42 = 74
Y 203, 2004 = 42+56 = 98
X:Y = 74:98 = 37:49
Which village plant more number of plants in 2003 and what is the difference between number of plants planted by both villages in 2003 ?
X = 36
Y = 42
Diff = 42 – 36 =6
Number of mobile phones sold by branch C is what percentage of the Total Number of mobile phones sold in 2006 ?
2006, C = 110
2006 Total = 105+65+110+95+95+80 = 550
% = (110/550)×100 = 20%
Direction -(11-15) :Study the information carefully to answer the given questions.
In a college out of 600 students, boys and girls are in the ratio 8: 7. Each students went to either physics lab or chemical lab or both, 40% of the boys attend only physics lab, total 20% children went to both the labs out of which 25% are boys, 45% of the girls went to only chemistry lab.
Que. Total how many boys went to only physics lab ?
8:7 = 320(boys):280(girls)
20% both = 20*600/100 = 120
B – (phy ) = 40*320/100 = 128
B – (both) = 25*120/100 = 30
G – (chem) = 45*280/100 = 126
Total no of boys(phy) = 128+30 = 158
Que. How many girls went to only physics lab ?
No of girls (phy) = (280-126 – 90) = 64
Que. Total number of students went to physics lab is what percentage of the total number of students in the college.
Total no of students went to only phy = 128+64 = 192
% = 192*100/600 = 32%
Que. What is the total number of girls went to chemistry lab ?
Explanation :Total no of Girls(chem) = 126+90 = 216
Que. What is the total number of students went to only chemistry lab ?
Explanation :Total no of students(chem) = (320-128-30)B + 126G = 162 + 126 = 288
Direction-(16-20): Study the given information to answer the question given below.
Que. If 500 copies are published and the transportation cost on the amount to Rs.2,500 then what should be the selling price of the book so that the publisher can earn a profit of 25%.
10% = 2500
125% = 125*2500/10 = 31250
Sp of 1 book = 31250/500 =62.5
Que. If for an edition of the book, the cost of the paper is Rs.6250, then find the promotion cost for this edition ?
25% = 6250
10% = 10*6250/25 = 2500
Que. Find the degree corresponding to the Royalty.
R = 15%
Angle = (360*15)/100 = 54degree
Que. Which two expenditure together have central angle of 144 degree.
(x*360)/100 = 144
X = 144*100/360 = 40% = 25%(paper) + 15%(Royalty)
Que. Find the total cost to publish 350 book if binding cost is Rs.165.
20% = 165
100% = (100*165)/20 = 825
350 book = 825*350 = 2,88,750
