Solutions:
1. C) Interest = PRT/100
Where P = Principal, R = Rate of interest, T = Time
For the first two years in Scheme II of company A
Let the principal be P
Rate of interest = 9%
S.I. = (P × 9 × 2)/100 = 18P/100
For the next three years in Scheme IV of company C
Let the principal be P
Rate of interest = 10%
S.I. = (P × 10 × 3)/100 = 3P/10
Total interest = 18P/100 + 3P/10 = 48P/100
Total interest = Rs. 1200
48P/100 = 1200
P = Rs. 2500
2. C) The formula for annual compound interest, including principal sum, is:
CI = P (1 + r/100)^nt – P
For company D under Scheme II
Principal = Rs. 1,40,00
Rate of interest = 10%
Interest is calculated annually, n = 1
Time (t) = 2 years
C.I. = 140000(1 + (10/100))– 140000 = Rs. 29400
For company B under Scheme II
Interest = PRT/100
Where P = Principal, R = Rate of interest, T is the time for which money is borrowed/lent
Principal = Rs. 1,40,00
Rate of interest = 8%
Time (T) = 2 years
Interest = (140000 × 8 × 2)/100 = Rs. 22400
Difference between interests earned = 29400 22400 = Rs. 700
3. C) Under scheme IV for 1 year
Rate of interest = 10%
Principal = Rs. 20000
Interest = (20000 × 10 × 1)/100 = Rs. 2000
Total amount = 20000 + 2000 = Rs. 22000
Under scheme II for 1 year
CI = P (1 + r/100)^nt – P
Rate of interest = 8.5%
n = 1, t = 1 year, P = Rs. 22000
A = 22000(1 + 8.5/100)2 = Rs. 25898.95 = Rs. 25,899
4. A) For Harsh
Rate of interest = 9.5%
Interest = (40000 × 9.5 × 2)/100 = Rs. 7600
For Sagar
Rate of interest = 8%
CI = P (1 + r/100)^nt – P
P = Rs. 40000
t = 2 years, n = 1
C.I. = 40000(1 + 8/100)2 – 40000 = Rs. 6656
Harsh receives more interest i.e. = 7600 - 6656 = Rs. 944
5. B) For Company B under Scheme III,
P = Rs. 25000
t = 2 years
r = 9%
n = 2
C.I. = 25000(1 + 9/200)4 – 25000 = Rs. 4813
Company D under Scheme II,
P = Rs. 30000
t = 2 years; r = 10%; n = 1
C.I. = 30000(1 + 10/100)2 – 30000 = Rs. 6300
Total interest earned = 4813 + 6300 = Rs. 11113
(6 – 10): Common Explanation:
Total number of candidates = 10000
Candidates having experience in Public Sector Banks in rural area only = 500
Candidates having experience in Public Sector Banks in urban area only = 20% = 2000
Candidates having experience in Private Sector Banks in urban area only = 10% = 1000
Candidates having experience in Private Sector Banks in rural area only = 4% = 400
Candidates having experience in Public and private Sector Banks in urban area only = 2100
Candidates having experience in Public and private Sector Banks rural area only = 450
Candidates having no experience = 10000 - (500 + 2000 + 1000 + 400 + 2100 + 450) = 3550
6. C) For rural area
Total candidates = 500 + 400 + 450 = 1350
7. B) Total candidates having experience in public sector banks = 500 + 2000 + 2100 + 450 = 5050
8. C) Total number of candidates who have worked in urban areas = 2000 + 1000 + 2100 = 5100
required ratio = 2000/5100 = 20/51
9. C) Total candidates having experience in private sector in urban area = 1000 + 2100 = 3100
10. D) Candidates having no experience = 3550
Total candidates having experience working in both banks = 2100 + 450 = 2550
Percentage = (2550/3550) × 100 = 71.83% = 72%
11. E) The avg. of profits = Total Profits/No.of years
Total profits in 6 years = 30 + 15 + 45 + 50 + 60 + 55 = 255
So, avg = 255/6 = 42.5 crores = Rs 425000000
12. A) Profit% = (This year profit – Previou year profit)/Previous year Profit × 100
 Profit in year Profit in crores Profit % 2000 30 - 2001 15 -50% 2002 45 200% 2003 50 11% 2004 60 20% 2005 55 -8%
Comparing the magnitudes, we can say that the year of highest per cent increase / decrease in profit is 2002.
13. B) Income of company = expenditure + Profit
Expenditure = 45 crore
Profit in 2001 = 15 crores   (from line graph)
Thus, income = 45 + 15 = 60 crores = Rs 60,00,00,000
14. C) Income of company = expenditure + profit of a company
Therefore, expenditure in 2004 = 136 – 60 = 76    …(1)     {From line graph profit in 2004 = 60 }
Therefore profit percentage = Profit/Expenditure × 100 = 60/76 × 100 = 79%
15. D) Expenditure of a company = Income of a company + Profit by a company
Thus from the above formula, expenditure of a company in 2000 = 50 crores – 30 crores  { from line graph profit of company is 30 crores in 2000}
Expenditure of company in 2000 = 20 crores
Similarily, expenditure of company in 2003 = 95crores – 50 crores = 45 crores.
So, ratio of expenditure of company in 2000 to 2003 = 20/45 = 4/9
