Question : 1
The sum of money, that will give Rs.1 as interest per day at the rate of 5% per annum simple interest is
a) Rs.36500
b) Rs.3650
c) Rs.7300
d) Rs.730
Answer »Answer: (c)
Using Rule 1,
The sum of money will give Rs.365 as simple interest in a year.
S.I. = $\text"PRT"/100$
365 = ${P × 5 × 1}/100$
P = ${365 × 100}/5$ = Rs.7300
Question : 2
Rs.800 becomes Rs.956 in 3 years at a certain rate of simple interest. If the rate of interest is increased by 4%, what amount will 800 become in 3 years ?
a) Rs.1025
b) Rs.1020.80
c) Rs.1050
d) Rs.1052
Answer »Answer: (d)
Using Rule 1,
S.I. = 956 - 800 = Rs.156
Rate = ${S.I. × 100}/{Principal × Time}$
= ${156 × 100}/{800 × 3}$ = 6.5% per annum
New rate = 10.5%
S.I. = ${\text"Principal × Rate × Time"/100$
= ${800 × 3 × 10.5}/100$ = Rs.252
Amount = 800 + 252 = Rs.1052
Question : 3
A money lender finds that due to fall in the annual rate of interest 8% to 7$3/4$% , his yearly income diminishes by Rs.61.50. His capital is
a) Rs.23800
b) Rs.22400
c) Rs.26000
d) Rs.24600
Answer »Answer: (d)
Difference in rate
= $(8 - 7{3}/4)% = 1/4$%
Let the capital be Rs.x.
$1/4$% of x = 61.50
x = 61.50 × 100 × 4 = Rs.24600
Question : 4
A man took a loan from a bank at the rate of 12% per annum at simple interest. After 3 years he had to pay Rs.5,400 as interest only for the period. The principal amount borrowed by him was :
a) Rs.10,000
b) Rs.2,000
c) Rs.15,000
d) Rs.20,000
Answer »Answer: (c)
Using Rule 1,
Let the principal be x.
S.I. = ${\text"Principal × Rate × Time"/100$
5400 = ${x × 12 × 3}/100$
$x = {5400 × 100}/{12 × 3}$ = Rs.15000
Question : 5
A sum of Rs.1600 gives a simple interest of Rs.252 in 2 years and 3 months. The rate of interest per annum is:
a) 8%
b) 5$1/2$%
c) 6%
d) 7%
Answer »Answer: (d)
Using Rule 1,
Principal (P) = Rs.1600
T = 2 years 3 months
= $(2 + 3/12) yrs. = (2 + 1/4) yrs. = 9/4 yrs.$
S.I = Rs.252
R = % rate of interest per annum
R = ${100 × S.I.}/{P × t}$
= ${100 × 252}/{1600 × 9/4}$
Rate of interest = 7% per annum.
Question : 6
A man had Rs.16,000, part of which he lent at 4% and the rest at 5% per annum simple interest. If the total interest received was Rs.700 in one year, the money lent at 4% per annum was
a) Rs.8,000
b) Rs.12,000
c) Rs.6,000
d) Rs.10,000
Answer »Answer: (d)
Using Rule 1,
Let the sum lent at 4% = Rs.x
Amount at 5%= (16000 - x )
According to the question,
${x × 4 × 1}/100 + {(16000 - X) × 5 × 1}/100$ = 700
4x + 80000 - 5x = 70000
x = 80000 - 70000 = Rs.10000
