Question : 1
A sum of Rs.1500 is lent out in two parts in such a way that the simple interest on one part at 10% per annum for 5 years is equal to that on another part at 12.5% per annum for 4 years. The sum lent out at 12.5% is :
a) Rs.1000
b) Rs.500
c) Rs.1250
d) Rs.750
Answer »Answer: (d)
Using Rule 1,
Let the sum lent out at 12.5% be x
Sum lent out at 10% = 1500 - x
Now, ${(1500 - x) × 10 × 5}/100$
= ${x × 12.5 × 4}/100$
50 (1500 - x ) = 50x
2x = 1500
$x = 1500/2$ = Rs.750
Question : 2
Mohan lent some amount of money at 9% simple interest and an equal amount of money at 10% simple interest each for two years. If his total interest was Rs. 760, what amount was lent in each case ?
a) Rs.1800
b) Rs.1700
c) Rs.2000
d) Rs.1900
Answer »Answer: (c)
Using Rule 1,
Let the sum lent in each case be x.
Then, ${x × 9 × 2}/100 + {x × 10 × 2}/100$ = 760
${x × 2}/100$(9 + 10) = 760
${2 × 19x}/100$ = 760
$x = {760 × 100}/{2 × 19}$ = Rs.2000
Question : 3
Simple interest on Rs.500 for 4 years at 6.25% per annum is equal to the simple interest on Rs.400 at 5% per annum for a certain period of time. The period of time is
a) 5 years
b) 4 years
c) 8$2/3$ years
d) 6$1/4$ years
Answer »Answer: (d)
Using Rule 1,
Let the period of time be T years. Then,
${400 × 5 × T}/100 = {500 × 4 × 6.25}/100$
T = ${500 × 4 × 6.25}/{400 × 5}$
= $25/4 = 6{1}/4$ years
Question : 4
In how many years will the simple interest on a sum of money be equal to the principal at the rate of 16$2/3$% per annum ?
a) 5 years
b) 4 years
c) 8 years
d) 6 years
Answer »Answer: (d)
Using Rule 1,
Let the principal be x.
Time = $\text"SI × 100"/\text"Principal × Rate"$
= ${x × 100 × 3}/{x × 50}$ = 6 years
Question : 5
Equal sum of money are lent to X and Y at 7.5% per annum for a period of 4 years and 5 years respectively. If the difference in interest, paid by them was Rs.150, the sum lent to each was
a) Rs.1000
b) Rs.500
c) Rs.3000
d) Rs.2000
Answer »Answer: (d)
Let the sum lent be x.
${x × 7.5 × 5}/100 - {x × 7.5 × 4}/100 = 150$
${x × 7.5 × 1}/100$ = 150
$x = {150 × 100}/{7.5}$ = Rs.2000
Using Rule 13,
Here, $P_1 = P, R_1 = 7.5%, T_1$ = 4 years.
$P_2 = P, R_2 = 7.5%, T_2$ = 5 years.
S.I. = Rs.150
S.I. = ${P_2R_2T_2 - P_1R_1T_1}/100$
150 = ${P × 7.5 × 5 - P × 7.5 × 4}/100$
15000 = 7.5P
P = $15000/{7.5}$
P = $150000/75$ = Rs.2000
Question : 6
A sum of Rs.1750 is divided into two parts such that the interests on the first part at 8% simple interest per annum and that on the other part at 6% simple interest per annum are equal. The interest on each part (In rupees) is
a) 65
b) 60
c) 40
d) 70
Answer »Answer: (b)
Using Rule 1,
Let first part be x and second part be(1750 –x )
According to the question,
x × $8/100 = (1750 - x ) × 6/100$
8x + 6x = 1750 × 6
14x = 1750 × 6
$x = {1750 × 6}/14$ = Rs.750
Interest = 8% of 750
= 750 × $8/100 = Rs.60
