- Madhava invested Rs. 1500 in Company 'B' in 2005 for two years with a condition to get the compound interest at the same rate as 2005. What was the amount of interest earned?
Options- A. Rs. 4387.75
- B. Rs. 4578.50
- C. Rs. 4578.75
- D. Rs. 4837.50
- Correct Answer
- Rs. 4837.50
ExplanationCompound interest = P(1 + r)t - P
or Compound interest = P[(1 + r)t - 1]
where P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate
t = the number of years the money is invested or borrowed for.
Required amount of interest earned by Madhava in 2007 = 15000[(1+ 15/100)2 - 1]
= 15000[(115/100)2 - 1]
= 15000[(23/20)2 - 1]
= 15000[(23 x 23 /20 x 20) - 1]
= 15000[ (529/400) - 1]
= 15000[(529 - 400)/400]
= 15000 x 129/400
= 19350/4

Correct Answer: 2 : 1
Explanation:
Correct Answer:
Explanation:
Given relationship is (PQ)(RQ) = XXX
Since X can take 9 values from 1 to 9 hence we have 9 possibilities
111 = 3 x 37 444 = 12 x 37 777 = 21 x 37
222 = 6 x 37 555 = 15 x 37 888 = 24 x 37
333 = 9 x 37 666 = 18 x 18 999 = 27 x 37
But out of these 9 cases only in 999, we get the unit's digit of two numbers the same. Since it is a unique value, hence we need neither statement I nor statement II to answer the question.

Correct Answer: 28190
Explanation:
Number of employees working in different organisation are
A ? 1050 + 1017 + 1382 + 1542 + 786 + 48 = 5825
B ? 1015 + 960 + 1384 + 1545 + 745 + 54 = 5703
C ? 976 + 786 + 1275 + 1550 + 801 + 36 = 5424
D ? 888 + 1025 + 1300 + 1570 +800 + 30 = 5613
E ? 1004 + 963 + 1290 + 1580 + 735 + 53 = 5625
Hence, total number of employees = 5825 + 5703 + 5424 + 5613 + 5625 = 28190
Correct Answer: 20
Explanation:
In 2008, number of students in Engineering = Total Student x 18%
In 2008, the number of students in Engineering = 35000x18/100 = 6300
In 2009, number of students in Engineering = Total Student x 19%
In 2009, the number of student in Engineering =40000 x19/100 = 7600
Required percentage = (number of students in Engineering in 2009 - number of students in Engineering 2008) x 100 / number of students in Engineering in 2008
Required percentage = (7600 - 3600)x 100 /6300 = 1300/63 = 20.6 ? 20%
Correct Answer:
Explanation:
It is 36.8% approximately.
