Required ratio = (440 - 410) : (570 - 10 - 440) = 30 : 120 = 1 : 4
By visual inspection it is clear that 1992 is the desired year (as the distance between two points is the maximum in 1992).
Hence , Required answer will be 1992.
From above given graph ,
According to given option in question , Maximum expenditure of the family is on food ,which is 23%.
We can not find out the amount of profit in 1998, we do not know the income and expenditure of A and B, therefore option (d) is the correct choice.
From I: There are two possible arrangetments.
(a) P T R S
(B) P T R S
So, either T or R
From II: There are two possible arrangements.
(a) Q T S
(b) T S Q
Again either T or S
Combining I and II
From I: n Suresh = 12th from left
Mohan = 17th from right = (50 - 17 + 1 = ) 34th from left
No student between them = 34 - 12 - 1 = 21
From II: No data about Mohan.
Here, 35% = Rs. 17500
Since, 15% = (17500/35 ) x 15 = Rs. 7500
Hence, required commission = Rs. 7500
Total number of students of class IX of schools Q and R = Total number of students of class IX of (Schools Q + school R)
Total number of students of class IX of schools Q and R = 157 + 143 = 300
Total number of students of class VI of schools S and T = Total number of students of class VI of ( School S + School T)
Total number of students of class VI of schools S and T = 142 + 144 = 286
Hence, required ratio = 300 : 286 = 150 : 143
We can apply the formula to calculate the interest amount
I = P x R x t where
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Rate of Interest per year as a percent;
t = Time Period involved in years
For Company A in 2006,
Principle amount = 10000
Rate of interest = 11.5 % ( As per given graph for company A in 2006)
Time = 1 year
The interest amount received by Samir in 2007 I = P x R x t
The interest amount received by Samir in 2007 = 10000 x 11.5 x 1/100= 10000 x 115 x 1/10 x 100 = 10 x 115 = 1150
Total amount received by Samir in 2007 = Interest amount + Principal amount = 10000 + 1150 = 11150
Again For Company A in 2007,
Principle amount = 11150
Rate of interest = 15 % ( As per given graph for company A in 2007)
Time = 1 year
The interest amount received by Samir in 2008 I = P x R x t
The interest amount received by Samir in 2008 = 11150 x 15 x 1/100 = 1115 x 15/10 = 1115 x 3/2 = 3345/2 = 1672.5
Total amount received by Samir in 2008 = Interest amount + Principal amount = 11150+ 1672.5 = 12822.50
Hence, their interest = 12822.50 - 10000 = 2822.50
For Company B in 2006,
Principle amount = 10000
Rate of interest = 13.5 % ( As per given graph for company B in 2006)
Time = 1 year
The interest amount received by Samir in 2007 I = P x R x t
The interest amount received by Samir in 2007 = 10000 x 13.5 x 1/100= 10000 x 135 x 1/10 x 100 = 10 x 135 = 1350
Total amount received by Samir in 2007 = Interest amount + Principal amount = 10000 + 1350 = 11350
Again For Company B in 2007,
Principle amount = 11350
Rate of interest = 14 % ( As per given graph for company B in 2007)
Time = 1 year
The interest amount received by Samir in 2008 I = P x R x t
The interest amount received by Samir in 2008 = 11350 x 14 x 1/100 = 1135 x 14/10 = 1135 x 7/5 = 227 x 7 = 1589
Total amount received by Samir in 2008 = Interest amount + Principal amount = 11350+ 1589 = 12939
Since, their interest = 12939 - 10000 = Rs. 2939
Hence, difference between the interests earned = 2939 - 2822.50 = Rs. 116.50
If Samir had invested the amount in company B for both years then he would get Rs. 116.50 more.
