7.	If the semi-annual compound interest of Rs15625 for 1 year 6 months is Rs 1951, find the rate of interest.
Answer» Given: The semi-annual COMPOUND INTEREST of Rs. 15625 for 1 year 6 months is Rs. 1951 To find: The rate of interest Solution: To SOLVE the given problem we will use the FOLLOWING formula of HALF-yearly compound interest: $\boxed{\bold{A = P [1 + \frac{\frac{R}{2}}{100} ]^2^n}}\\\\\boxed{\bold{C.I. = A - P}}$ Here we have C.I. = Rs. 1951 P = Rs. 15625 n = $1\frac{6}{12} = 1\frac{1}{2} = \frac{3}{2} \:years$ Now, using the above two formulas, we get $C.I. = P [1 + \frac{\frac{R}{2}}{100} ]^2^n - P$ substituting the given values $\implies 1951 = 15625 [1 + \frac{\frac{R}{2}}{100} ]^2^(^\frac{3}{2}^ ) - 15625$ $\implies 1951 + 15625 = 15625 [1 + \frac{\frac{R}{2}}{100} ]^3$ $\implies 17575 = 15625 [1 + \frac{R}{200} ]^3$ $\implies \frac{17575}{15625} = [1 + \frac{R}{200} ]^3$ taking cube roots on both sides $\implies \sqrt[3]{\frac{17575}{15625}} = \sqrt[3]{[1 + \frac{R}{200} ]^3}$ $\implies {\frac{26}{25} = [1 + \frac{R}{200} ]$ $\implies {\frac{26}{25} - 1 = \frac{R}{200}$ $\implies {\frac{26-25}{25} = \frac{R}{200}$ $\implies {\frac{1}{25} = \frac{R}{200}$ $\implies R = \frac{200}{25}$ $\implies \bold{R = 8\%}$ Thus, the rate of interest is → 8%. --------------------------------------------------------------------------------- Also View: What will be the compound interest on 5,000, if it is compounded half-yearly for 1 year 6 months at 8% per annum? brainly.in/question/12296626 What will Rs.80,000 amount to in 2 years at the rate of 20% p.a., if interest is compounded half yearly? brainly.in/question/12159582 Principal= ₹ 2560 Rate = 25/2% Time = 1 Year calculate the amount and C.I. if the interest is compounded half yearly. brainly.in/question/13435421

If the semi-annual compound interest of Rs15625 for 1 year 6 months is Rs 1951, find the rate of interest.

Answer» Given:

The semi-annual COMPOUND INTEREST of Rs. 15625 for 1 year 6 months is Rs. 1951

To find:

The rate of interest

Solution:

To SOLVE the given problem we will use the FOLLOWING formula of HALF-yearly compound interest:

$\boxed{\bold{A = P [1 + \frac{\frac{R}{2}}{100} ]^2^n}}\\\\\boxed{\bold{C.I. = A - P}}$

Here we have

C.I. = Rs. 1951

P = Rs. 15625

n = $1\frac{6}{12} = 1\frac{1}{2} = \frac{3}{2} \:years$

Now, using the above two formulas, we get

$C.I. = P [1 + \frac{\frac{R}{2}}{100} ]^2^n - P$

substituting the given values

$\implies 1951 = 15625 [1 + \frac{\frac{R}{2}}{100} ]^2^(^\frac{3}{2}^ ) - 15625$

$\implies 1951 + 15625 = 15625 [1 + \frac{\frac{R}{2}}{100} ]^3$

$\implies 17575 = 15625 [1 + \frac{R}{200} ]^3$

$\implies \frac{17575}{15625} = [1 + \frac{R}{200} ]^3$

taking cube roots on both sides

$\implies \sqrt[3]{\frac{17575}{15625}} = \sqrt[3]{[1 + \frac{R}{200} ]^3}$

$\implies {\frac{26}{25} = [1 + \frac{R}{200} ]$

$\implies {\frac{26}{25} - 1 = \frac{R}{200}$

$\implies {\frac{26-25}{25} = \frac{R}{200}$

$\implies {\frac{1}{25} = \frac{R}{200}$

$\implies R = \frac{200}{25}$

$\implies \bold{R = 8\%}$

Thus, the rate of interest is → 8%.

The population of a town increases 15% every year. If the present population is 20700, find the population a year ago

Answer»

ong>

Answer: the population a year before was 18000.

Step-by-step explanation:

rate of increase in population (R) = 15%

time= 1 yrs.

since, the population given is of present (A)= 20700

population a year ago (P)= ?

we know,

A = P (1+r/100)^{n}

20700 = P [(1 + 15/100)^{1}]

20700 =P (1+ 3/20)

20700 = p {(20+3)/20}

P = 20700 (20/ 23)

P = 20700*20/23

P = 900*20

P = 18000 (ans) solved.

YOUVEIn AABC, LA = 16, LB 44° then LC = ?

Answer» ONG>Answer:

By angle sum property of a triangle

angle 1 + angle 2 + angle 3 = 180

16 + 44 +angle C = 180

60 +angle C = 180

angle C = 180 - 60

angle C = 120...

43.	On reversing the digits of a digits numbernumber obtained as 9less than3 timethe orginal number. If differenceofthese2 number is 45 find theorginal sumber.
Answer» ong>Answer: $\bigstar{\bold{Original\:number=27}}$ Step-by-step explanation: $\Large{\underline{\underline{\bf{Given:}}}}$ Reversing the digits, the number OBTAINED is 9 less than 3 times the original umber Difference of these two numbers = 45 $\Large{\underline{\underline{\bf{To\:Find:}}}}$ The original number $\Large{\underline{\underline{\bf{Solution:}}}}$ → Let the ten's digit be X → Let the unit's digit be y → Hence the number would be 10x + y → Reversing the number, Reversed number = 10y + x → By given 10y + x = 3 (10x + y) - 9 10y + x = 30x + 3y - 9 10y -3y = 30x - x - 9 7y = 29 x - 9 29x - 7y - 9 = 0 ------(1) → Also by given 10y + x - (10x + y) = 45 10y + x -10x - y =45 9y - 9x = 45 → Dividing the whole equation by 9 y - x = 5 y = 5 + x ----(2) → Substitute equation 2 in equation 1 29x - 7(5 + x) - 9 = 0 29x - 35 - 7x - 9 = 0 22X - 44 = 0 22x = 44 x = 44/22 x = 2 → Hence the ten's digit is 2 → Substitute the VALUE of x in 2 y = 5 + 2 y = 7 → The unit's digit is 7 → Hence the number is 2 × 10 + 7 The number = 20 + 7 The number = 27 $\boxed{\bold{Original\:number=27}}$ $\Large{\underline{\underline{\bf{Verification:}}}}$ → By the first case, 10y + x = 3 (10x + y) -9 10 × 7 + 2 = 3 (10 × 2 + 7) - 9 70 + 2 = 3 ( 20 + 7) -9 72 = 3 ( 27) - 9 72 = 81 - 9 72 = 72 → Difference of the reversed and orginal number = 45 10y + x - (10x + y) = 45 10 × 7 + 2 - (10 × 2 + 7) = 45 70 + 2 - (20 + 7) = 45 72 - 27 = 45 45 = 45 → Hence verified.

On reversing the digits of a digits numbernumber obtained as 9less than3 timethe orginal number. If differenceofthese2 number is 45 find theorginal sumber.

Answer»

ong>Answer:

$\bigstar{\bold{Original\:number=27}}$

Step-by-step explanation:

$\Large{\underline{\underline{\bf{Given:}}}}$

Reversing the digits, the number OBTAINED is 9 less than 3 times the original umber
Difference of these two numbers = 45

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

The original number

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ Let the ten's digit be X

→ Let the unit's digit be y

→ Hence the number would be 10x + y

→ Reversing the number,

Reversed number = 10y + x

→ By given

10y + x = 3 (10x + y) - 9

10y + x = 30x + 3y - 9

10y -3y = 30x - x - 9

7y = 29 x - 9

29x - 7y - 9 = 0 ------(1)

→ Also by given

10y + x - (10x + y) = 45

10y + x -10x - y =45

9y - 9x = 45

→ Dividing the whole equation by 9

y - x = 5

y = 5 + x ----(2)

→ Substitute equation 2 in equation 1

29x - 7(5 + x) - 9 = 0

29x - 35 - 7x - 9 = 0

22X - 44 = 0

22x = 44

x = 44/22

x = 2

→ Hence the ten's digit is 2

→ Substitute the VALUE of x in 2

y = 5 + 2

y = 7

→ The unit's digit is 7

→ Hence the number is 2 × 10 + 7

The number = 20 + 7

The number = 27

$\boxed{\bold{Original\:number=27}}$

$\Large{\underline{\underline{\bf{Verification:}}}}$

→ By the first case,

10y + x = 3 (10x + y) -9

10 × 7 + 2 = 3 (10 × 2 + 7) - 9

70 + 2 = 3 ( 20 + 7) -9

72 = 3 ( 27) - 9

72 = 81 - 9

72 = 72

→ Difference of the reversed and orginal number = 45

10y + x - (10x + y) = 45

10 × 7 + 2 - (10 × 2 + 7) = 45

70 + 2 - (20 + 7) = 45

72 - 27 = 45

45 = 45

→ Hence verified.
