Average annual exports of Company Z during the given period
= 1/7 x (60 + 90 + 120 + 90 + 60 + 80 + 100)
= Rs. ( 600 /7)crores
= Rs. 85.71 crores.
From the analysis of graph the exports of Company Z are more than the average annual exports of Company Z (i.e., Rs. 85.71 crores) during the years 1994, 1995, 1996 and 1999, i.e., during 4 of the given years.

Roy Kunal Singh answered |
Simple,
Total Income = 342 cr
Income in percentage = 140+145=285%
Expenditure per year= 200×342/285 = 240 cr
So total profit in 1996 = 342 - 240 = 102 cr
Total Income = 342 cr
Income in percentage = 140+145=285%
Expenditure per year= 200×342/285 = 240 cr
So total profit in 1996 = 342 - 240 = 102 cr

In Assam = 2.7
Rajasthan in the year 2005, 2007 and 2008 together = 0.7 + 1.8 + 2.2 = 4.7
so difference = 4.7 - 2.7 = 2
as in hundreds so 200

To find the average number of failed students of Class 8th , we need to first add up the number of failed students
= 11+6+9+12+10+5+3= 56
Now total number of years = 7
Average = 56/7= 8
= 11+6+9+12+10+5+3= 56
Now total number of years = 7
Average = 56/7= 8

Anaya Patel answered |
The correct answer is D
In 1999 , profit % of X = 50
profit% of Y = 60
Also , let their income in 1999 be i each and expenditure of X be x and that of Y be y.
For X ,
50 = (i - x)*100/x
1/2 = (i - x)/x
x/2 = i - x
i = 3x/2 (eq1)
For Y ,
60 = (i - y)*100/y
3/5 = (i - y)/y
3y/5 = i - y
i = 8y/5(eq 2)
Equating eq 1and 2 , we get
3x/2 = 8y/5
x/y = 16/15
x : y = 16:15

Dia Mehta answered |
The correct answer is C
Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively.
And let the expenditures in 2000 of Companies X and Y be E1 and E2 respectively.
Then, for Company X we have:
65 =[( 3x - E1 )/E1]×100 =>65/100 = (3x/E1) - 1
=> E1 = 3x×( 100/165 ) .... (i)
For Company Y we have:
50 = [(4x - E2 )/E2]x 100 =>50/100= (4x/E1) - 1 => E2 = 4x×( 100/150 ) .... (ii)
From (i) and (ii), we get:
E1/E2=[3x ×(100/165)]/[4x×(100/150)]
E1/E2=15/22 (required ratio)
Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively.
And let the expenditures in 2000 of Companies X and Y be E1 and E2 respectively.
Then, for Company X we have:
65 =[( 3x - E1 )/E1]×100 =>65/100 = (3x/E1) - 1
=> E1 = 3x×( 100/165 ) .... (i)
For Company Y we have:
50 = [(4x - E2 )/E2]x 100 =>50/100= (4x/E1) - 1 => E2 = 4x×( 100/150 ) .... (ii)

Candidates qualified by institution B in 2002 by graph let X = 3.5×1000= 3500
Candidates qualified by institution A in 2006 by graph let Y = 4×1000 = 4000
Rati of X&Y = X:Y = 3500:4000 = 7:8
Hence option 'C' is correct
Candidates qualified by institution A in 2006 by graph let Y = 4×1000 = 4000

Explanation:
Q’s 5 days work = 50%
S’s 5 days work = 33.33%
M’s 2 days work = 16.66% [100- (50+33.33)] Ratio of work of Q, S and M = 3: 2: 1
Q’s total share = Rs. 3000
S’s total share = Rs. 2000
M’s total share = Rs. 1000
Q’s one day’s wage = Rs.600
S’s one day’s wage = Rs.400
M’s one day’s wage = Rs.500
Q’s 5 days work = 50%
S’s 5 days work = 33.33%
M’s 2 days work = 16.66% [100- (50+33.33)] Ratio of work of Q, S and M = 3: 2: 1
Q’s total share = Rs. 3000
S’s total share = Rs. 2000
M’s total share = Rs. 1000
Q’s one day’s wage = Rs.600
S’s one day’s wage = Rs.400
M’s one day’s wage = Rs.500

Efficiency of R = (100/50) = 2%
Rest work = 75%
∴ Efficiency of Z = 75/25 = 3%
∴ Combined efficiency of R and Z = 5%
∴ Number of days required by R and Z to work together = 100/5 = 20 days.

Efficiency of T and V = 11.11 + 5.55 = 16.66%
Work done in 3 days = 3 x 16.66 = 50%
Rest work done by T, V and Z = 50/50 = 1 day
Work can be completed in 4 days.
Work done in 3 days = 3 x 16.66 = 50%

Efficiency of P = 4%
Efficiency of R = 2%
[(4+2)*10] = 60%
The remaining work was done by U = 40%.
40% of 600 = 240
Efficiency of R = 2%
[(4+2)*10] = 60%
The remaining work was done by U = 40%.
40% of 600 = 240

X, Y and R’s 1 day work = 1/10 + 1/50 = 6/50 = 3/25
X’s 1 day work = Y + R‘s 1 day work
2*( x’s 1 day work) = 3/25
x’s 1 day work = 3/50
Y’s 1 day work = 1/10 – 3/50 = 2/50 = 1/25
X’s 1 day work = Y + R‘s 1 day work
2*( x’s 1 day work) = 3/25
x’s 1 day work = 3/50
Y’s 1 day work = 1/10 – 3/50 = 2/50 = 1/25
