Find the amount and the compound intrest on 5000 for 1 and half year at 8% per annum, the intrest being compound semi-annually.

Answer»

ANSWER:

MATHS

Find the compounded interest on Rs. 5000 for 1 year 8% per ANNUM, compounded half-yearly.

ANSWER

Given, Pricnipal=Rs. 5000

Rate =8%

Time =1 year, ⟹n=2∵ Compounded half-yearly

A=P(1+2.100r)n

A=5000(1+2008)2

A=5000(200208)(200208)

A=5408

C.I=A−P

=5408−5000

=408

C.I.=408.

AB is a chord of circle substending an angle 90 degrees at the center O of the circle If the radius of the circle is 6cm the area of minor segment is

Answer»

Answer:

area of minor sector = area of chord - area of triangle

area of chord = (Ф /360) X πr^2 = 9π

area of triangle = 1/2 x B x h = 1/2 x 6 x 6 = 18

Plot numbers from 1 to 9 without repeating

Answer»

Given : _ _x_=_ _+_ _=_ _ ( 9 blanks paces )

To find : Blank spaces to be filled with 1 to 9 Digits

Solution:

AB * C = DE + FG = HI

Here AB * C = DE ( is one operation)

DE + FG = HI ( another operation)

there is no linkage directly between AB & HI

A to I digit 1 to 9

17 x 4 = 68 + 25 = 93

17 * 4 = 68

68 + 25 = 93

17

* 4

____

68

+ 25

______

93

Here is how we reached to solution

All digits used from 1 to 9

ab* c = de

de + fg = hi

1 to 9 digit

hi TWO digit

b , c can not be 1 or 5

as ab * 1 = ab => ab = de ( with same digits)

a1 * c will end with c a5 * c will end with 5 or 0

ab * 5 will end with 0 or 5 ( 0 not available , 5 will be repeated digit in c & i)

Let s check all possible

11 , 12 * 1 , 12 * 2 , 12 * 3 = 36 , 12 * 4 = 48 , 12 * 5 ,12*6 = 72 , 12 * 9 = 108 ( not possible)

17 * 1 , 17*3 = 51 , 17 * 5 , 17 * 6 = 102 ( not possible)

17 * 2 = 34 remaining digits 5 , 6 , 8 , 9 not satisfied

17 * 4 = 68 remaining digits 2 , 3 , 5 , 9 (68 + 25 = 93)

A number is divided into five parts. Twice the firstpart, thrice the second part and four times the fourthpart are equal. Twice the second part, five times thethird part and six times the last part are equal. Which ofthe following is always true if all the parts are integers?(A) The first part is a multiple of 72.(B) The second part is divisible by the fourth part.(C) The first part is a factor of the last part.(D) The product of the first and fourth parts isdivisible by 30.

Answer»

Answer:

only c is true.

Step-by-step explanation:

let 5 parts be a,b,c,d,e

from 1st STATEMENT, 2a = 3b = 4d

from 2nd statement, 2b = 5c = 6e

hence we can say 4a = 6b = 15C = 8d = 18e

dividing by 720,

we can say numbers r in ratio

90:60:24:45:20

a)The first part is a multiple of 72

false

b)The second part is divisible by the FORTH part

false

c)the PRODUCT of the first and fourth parts is divisible by 30

true

d)the first part is a factor of the last part

false

Show that the lengths of tangents drawn from an external point to a circle are equa

Answer»

ANSWER:

Hey!! Here is your answer.....

Statement :- The lengths of tangents drawn from an external point to a circle are equal.

Given :- A circle with centre o, p is a point lying outside the circle and PA and PB are two tangents to the circle from p.

To PROVE :-PA=PB.

Proof :- Join OA, OB and OP.

ANGLE OBP = Angle OAP = 90

(Angle between tangent and radius is 90)

Now in ∆OAP and in ∆OBP

OA = OB(RADII of the same circle)

OP=OP

∆OAP congruent ∆ OBP(R. H. S congruence)

:. PA=PB ( CPCT)

Hence proved.

given that x-y=12

7y/5 - y = 12

2y=60

y=30

by substituting in the above equation we get,

7(30)=5x

x=42

38.	A gardener planted trees is rows and columns such that the number of rows is five more then the number of columns.if the total number of rows and columns is 110,find the number of trees?
Answer» Answer:The question seems a BIT wrong pls VERIFY, HOWEVER i did it with the information given. The total number of TREES comes out to be 12075/4. Step-by-step explanation: Let the number of rows be x and number of columns be y. From the question, we know number of rows is 5 more than number of column. Hence x = y + 5 This can be written as x - y = 5 --(1) Its ALSO given total number of rows and column are 110, hence x + y = 110 --(2) From (1) & (2), 2x = 115 x = 115/2 Thus y = 110-(115/2) => (220-115)/2 => 105/2 Hence there are 115/2 rows and 105/2 columns. Thus number of trees would be:- 115/2*105/2 => 12075/4.

A gardener planted trees is rows and columns such that the number of rows is five more then the number of columns.if the total number of rows and columns is 110,find the number of trees?

Answer»

Answer:The question seems a BIT wrong pls VERIFY, HOWEVER i did it with the information given. The total number of TREES comes out to be 12075/4.

Step-by-step explanation:

Let the number of rows be x and number of columns be y.

From the question, we know number of rows is 5 more than number of column. Hence

x = y + 5

This can be written as x - y = 5 --(1)

Its ALSO given total number of rows and column are 110, hence

x + y = 110 --(2)

From (1) & (2),

2x = 115

x = 115/2

Thus y = 110-(115/2)

=> (220-115)/2

=> 105/2

Hence there are 115/2 rows and 105/2 columns.

Thus number of trees would be:- 115/2*105/2

=> 12075/4.
