Q31-35: Two different finance companies, P and Q, offer fixed annual interest rates on investments. These rates can vary each year, influenced by the country’s economic conditions and prevailing bank interest rates. The line graph below illustrates the annual interest rates provided by Companies P and Q over the years.
Annual Rate of Interest Offered by Two Finance Companies Over the Years.
31. A sum of Rs. 4.75 lakhs was invested in Company Q in 1999 for one year. How much more interest would have been earned if the sum was invested in Company P?
a) Rs. 19,000
b) Rs. 14,250
c) Rs. 11,750
d) Rs. 9,500
Answer: d) Rs. 9,500
Explanation:
Difference = Rs. [(10% of 4.75) – (8% of 4.75)] lakhs
= Rs. (2% of 4.75) lakhs
= Rs. 0.095 lakhs
= Rs. 9,500.
32. If two different amounts in the ratio 8:9 are invested in Companies P and Q respectively in 2002, then the amounts received after one year as interests from Companies P and Q are respectively in the ratio?
a) 2:3
b) 3:4
c) 6:7
d) 4:3
Answer: d) 4:3
Explanation:
Let the amounts invested in 2002 in Companies P and Q be Rs. 8x and Rs. 9x respectively.
Interest received from Company P = Rs. (6% of 8x) = Rs. 0.48x
Interest received from Company Q = Rs. (4% of 9x) = Rs. 0.36x
Therefore, the ratio of interests = (0.48x) / (0.36x) = 4:3.
33. In 2000, a part of Rs. 30 lakhs was invested in Company P and the rest was invested in Company Q for one year. The total interest received was Rs. 2.43 lakhs. What was the amount invested in Company P?
a) Rs. 9 lakhs
b) Rs. 11 lakhs
c) Rs. 12 lakhs
d) Rs. 18 lakhs
Answer: d) Rs. 18 lakhs
Explanation:
Let Rs. x lakhs be invested in Company P and Rs. (30 – x) lakhs in Company Q.
Total interest = Rs. [(7.5% of x) + (9% of (30 – x))] lakhs
= Rs. [(0.075x) + (2.7 – 0.09x)]
= 2.7 – 0.015x = 2.43
Solving, x = 18 lakhs.
34. An investor invested a sum of Rs. 12 lakhs in Company P in 1998. The total amount received after one year was re-invested in the same Company for one more year. The total appreciation received by the investor on his investment was?
a) Rs. 2,96,200
b) Rs. 2,42,200
c) Rs. 2,25,600
d) Rs. 2,16,000
Answer: c) Rs. 2,25,600
Explanation:
Amount received from Company P after one year on Rs. 12 lakhs
= Rs. [12 + (8% of 12)] lakhs
= Rs. 12.96 lakhs.
Amount received after re-investing Rs. 12.96 lakhs
= Rs. [12.96 + (10% of 12.96)] lakhs
= Rs. 14.256 lakhs.
Appreciation = Rs. (14.256 – 12) lakhs
= Rs. 2.256 lakhs
= Rs. 2,25,600.
35. An investor invested Rs. 5 lakhs in Company Q in 1996. After one year, the entire amount along with the interest was transferred as investment to Company P in 1997 for one year. What amount will be received from Company P, by the investor?
a) Rs. 5,94,550
b) Rs. 5,80,425
c) Rs. 5,77,800
d) Rs. 5,77,500
Answer: b) Rs. 5,80,425
Explanation:
Amount received from Company Q after one year on Rs. 5 lakhs
= Rs. [5 + (6.5% of 5)] lakhs
= Rs. 5.325 lakhs.
Amount received from Company P after one year on Rs. 5.325 lakhs
= Rs. [5.325 + (9% of 5.325)] lakhs
= Rs. 5.80425 lakhs
= Rs. 5,80,425.

40. If in the year 1998, there was an increase of 10% in the population of U.P. and 12% in the population of M.P. compared to the previous year, then what was the ratio of populations of U.P. and M.P. in 1997?
(a) 42 : 55
(b) 48 : 55
(c) 7 : 11
(d) 4 : 5
Answer: 42 : 55
Explanation: Let x be the population of U.P. and y be the population of M.P. in 1997. Ratio of populations of U.P. and M.P. in 1998 = 110x / 112y. Given from the chart, this ratio is 15 / 20, leading to the ratio in 1997 as 42 : 55.

A. 60 m
B. 70 m
C. 80 m
D. 90 m
Answer: C. 80 m
Solution:
Speed=36 km/h
=36×1000/3600 m/s=10 m/s

A. 3 km/hr
B. 5 km/hr
C. 8 km/hr
D. 9 km/hr
Answer: C. 8 km/hr

Total Distance=60 m+84 m=144 m
Time= Distance/Speed
= 144 m/3.33 m/s
≈43.24 s
