## If Rs. 7500 are borrowed at C. I at the rate of 4 % per annum then after 2 years, the amount to be paid is ?

**A. Rs. 8112**B. Rs. 8100

C. Rs. 8082

D. Rs. 7800Amount = Rs. [7500 (1 +4/100)2]

= Rs. [7500 × 26/25 × 26/25] = Rs.8112

## Simple Interest on a sum at 4% per annum for 2 years is 80. The compound interest on the same sum for the same period is ?

A. Rs. 1081.60

B. Rs. 101.66**C. Rs. 81.60**D. Rs. 160## Rs. 800 at 5 % Per annum compound interest will amount to Rs. 882 in ?

**A. 2 years**B. 4 Years

C. 1 Year

D. 3 YearsTime be t years 882 = 800 (1 +5/100)

^{t}=> 882/800 =(21/20)

^{t}(21/20) 2 = (21/20)

^{t}=> t = 2 Therefore,

Time = 2 years

## What is the principle amount which earns Rs.132 as compound interest for the second year at 10 % per annum ?

A. Rs. 1720

B. Rs. 1000**C. Rs. 1200**D. Rs. 1120## Difference between the compound interest and the simple interest on a certain sum at 5 % per annum for 2 years is Rs. 1.50. The sum is ?

A. Rs.400

B. Rs.300**C. Rs.600**D. Rs.500S.I = Rs.(1000/100) =Rs.10

C.I = Rs.[{100 × (1 +5/100) 2} – 100] =Rs.41/4

Difference C.I amd S. I = Rs.(41/4 – 10) =Rs.25

25 : 1.50 : : 100 : x

Therefore x = ((1.50 ×100)/25) = Rs.600## Difference between simple interest and compound interest at the same rate for Rs.5000 for 2 years is Rs. 72. The rate of interest is ?

**A. 12 %**B. 8 %

C. 10 %

D. 6 %5000 × (1 +R/100) 2 – 5000 –(10000R/100)= 72

=> 5000 [(1 + R/100) 2 – 1 – R/50] = 72

=> 1 + R2/100 + 2R/100 – 1 – R/50 = 72/5000

=> R2 = (72/5000 × 10000) = 144 or R =12%## A sum of money amounts to Rs. 10648 in 3years and Rs. 9680 in 2 years. The rate of interest is ?

A. 15 %

B. 20 %

C. 5 %**D. 10 %**P(1 + R/100) 3 = 10648 – (i)

P(1 + R/100) 2 = 9680 – (ii)

By dividing (i) and (ii)

(1 +R/100) = 10648/9680 Or

R/100 = 968/9680 = 1/10 or

R = 10 %## A sum amounts to Rs. 2916 in 2 years and to Rs.3149.28 in 3 years at compound Interest. The sum is ?

**A. Rs.2500**B. Rs.3000

C. Rs.1500

D. Rs.2000P be the principle and R % per annum be rate

P(1 + R/100)

^{3}= 3149.28 – (i)P(1 + R/100)

^{2}= 2916 – (ii)

By dividing (i) and (ii)

(1 + R/100) = 3149.28/2916 R/100 = 233.28/2916

or R =233.28/2916 x 100 = 8 %

P(1 +8/100)^{2}= 2916 or

P × 27/25 × 27/25 = 2916

Or = 1822500/729= Rs.2500## A sum of money becomes Rs.6690 after three years and Rs.10.035 after six years on compound interest. The sum is ?

**A. Rs.4460**B. Rs.4520

C. Rs.4400

D. Rs.4445P(1 + R/100)

^{3}= 6690 – (i)

P(1 + R/100)^{2}= 10, 035 – (ii)

By dividing (i) and (ii)

(1 + R/100)^{3}= 10035/6690 = 3/2

Therefore, P = (6690 x 2/3) = Rs. 4460## Difference between the simple interest and the compound interest on Rs 5000 at 10% P.a for 3 years is :____ ?

A. Rs 150

B. Rs 165

C. Rs 145**D. None of these**
