Simple And Compound Interest
A tape recorder is sold for 3500₹ cash, or 1000 ₹cash down payment and the balance in three equal easy installments. If 12 1/2% is the rate of interest compounded annually, find the amount of installment.

a) 1100.45₹
b) 1049.83₹
c) 1000.35₹
d) 1050.65₹



Answer
Solution
Correct Answer Is : 1049.83₹
Solution Is : Let each installment be x Amount = 3500 - 1000 = 2500 x/( 1 + 25/200 ) + x/( 1 + 25/200)2 = x/( 1 + 25/200)3 = 2500 ⇒ 8/9x + (8/9)2x + (8/9)3 x = 2500 (8/9)x * [ 1+ 8/9 +64/81 ] = 2500 ⇒ (8/9)x * [ 81 + 72 + 64/81] = 2500 ⇒ (8/9)x * 217/81 = 2500 x = 2500 * 9 * 81/ 8 * 217 = 1049.83
A certain sum when invested at 5% interest compounded annually for 3 years yields an interest of Rs.2,522. Find the Principal?

a) Rs. 1`7,200
b) Rs. 16,000
c) Rs. 15,200
d) Rs . 12,522



Answer
Solution
Correct Answer Is : Rs. 16,000
Solution Is : CI = 2522 CI = P(1+r/100)n - P 2522 = P ( 1 + 5/100)3 -P 2522 = P ( 1+ 1/20)3 - P 2522 = P 21x21x21 / 20x20x20 - P 2522 = 1.1576 P - P 0.1576 P = 2522 P = 16,000
Find the difference between SI and CI on Rs2000 in 2 yr at 6% per annum.

a) Rs 7.30
b) Rs 7.10
c) Rs 7.00
d) Rs 7.20



Answer
Solution
Correct Answer Is : Rs 7.20
Solution Is : Using the formula D=P*(r/100)2 D=2000*(6/100)2 =2000*(36/100) =Rs 7.20
Anil lent Rs 1000 to soured for 4yr and Rs 3000 to Vinod for 2 yr. If he received Rs 900 as simple interest altogether, the rate of interest is

a) 5%
b) 7%
c) 8%
d) 9%



Answer
Solution
Correct Answer Is : 9%
Solution Is : Here p1=Rs 1000 p2=Rs 3000 Rate =r%, t1=4yr, t2=2yr Sum of SI=Rs 900 Using the formula SI=per/100 900=(p1t1r/100)+(p2t2r/100) 900=(1000*4*r/100)+(3000+2*r/100) r=900/100 %=9%
A sum of 800 becomes 956 in 3 years at a certain rate of simple interest. If the rate of interest is increased by 4%, What amount will the same sum become is 3 years ?

a) 1024
b) 1025
c) 1052
d) 1042



Answer
Solution
Correct Answer Is : 1052
Solution Is : A sum of 800 becomes 956 in 3 yr. We know that, A = P + SI 956 = 800 + 800 * r * 3/100 156 = 8 * r * 3, 156/3*8 = r, 52/8 = r, 13/2 = r If the rate of interest is increased by 4%. New Rate of interest = 13/2+ 4 So, amount = P + SI = 800 + 800 * ( 13/2 + 4 ) * 3 = 800 + 8 * 21/2 * 3 = 800 + 4 * 21 * 3 = 800 + 12 * 21 = 800 + 252 = 1052.
A certain sum amounts to 1725 at 15% per annum at simple interest and 1800 in the same time at 20% per annum at simple interest. Find the sum.

a) 1650
b) 1200
c) 1700
d) 1500



Answer
Solution
Correct Answer Is : 1500
Solution Is : A certain sum amount to 1725 at 15% per annum and in the same time the sum becomes 1800 at 20% per annum. According to the question, P + ( P * 20 * T/100) - p ( p * 15 * T/100 ) = 1800 - 1725 Since, time is same for both so, 20P/100 - 15P/100 = 75, 5P = 75 x 100, P = 1500.
