4.

If the Simple Interest earned on acertain sum of money at 6% perannum for 2 years is Rs.700, find theCompound Interest earned on thesame sum of money at the same ratefor 2 years?

Answer»

Step-by-step explanation:

p=700

r=6%

t=2 years.

formulae of C.I = [P*{1+R/100}^T] - P

PUTTING VALUES IN THE FORMULAE ;

[700*{1+6/100}^2]-700.

solving the equation

[700*{106/100}^2 ]-700.

[700*11236/10000]-700. (square of 106=11236, 100= 10000)

[7*11236/100]-700.

CANCELLATION of TWO ZEROS of 700 from zeros of 10000

now, multiplying 7 and 11236. we get

78,652/100 - 700.

786.52-700.

86.52.

HENCE C.I = 86.52.

10.	Given that xand yare positive realnumbers and xy= 100. If x increasesthen yincreasesnoneremain constantdecreases
Answer» Answer: 100/11% Step-by-step explanation: For inversely proportional numbers, the PRODUCT of the number must always be constant, if all other conditions are the same. Let x and y be both 10, then xy = Constant => 10x10 = Constant If x increases by 10%, then the new value of x will be 11. And the product of x and y will be 110. But product of x and y should be constant( 100 in this case.) Then y should be decrease to keep the product constant.Now, xy = 100 11y = 100 y = 100/11 And in PERCENTAGE terms [(10 - 100/11)/ 10] x 100 = (10/110) x 100 = 100/11 %

10.

Given that xand yare positive realnumbers and xy= 100. If x increasesthen yincreasesnoneremain constantdecreases

Answer»

Answer:

100/11%

Step-by-step explanation:

For inversely proportional numbers, the PRODUCT of the number must always be constant, if all other conditions are the same.

Let x and y be both 10,

then xy = Constant

=> 10x10 = Constant

If x increases by 10%, then the new value of x will be 11. And the product of x and y will be 110. But product of x and y should be constant( 100 in this case.) Then y should be decrease to keep the product constant.Now,

xy = 100

11y = 100

y = 100/11

And in PERCENTAGE terms

[(10 - 100/11)/ 10] x 100 = (10/110) x 100 = 100/11 %

22.	22. If a flag pole of 6 metres high placed on the top of a tower throws a shadow (shadowof polo only) of 2 3 m along the ground, then find the angle of elevation with the sun
Answer» Angle of elevation with the sun = 60⁰ Step-by-step explanation: There is an ERROR in the question. The length of the shadow should ACTUALLY be 2√3, not 23 m. In TRIANGLE ABC, let BC be the pole (perpendicular), then AC is the HYPOTENUSE and shadow of the pole is base AB. Given: Base = 2√3 m Perpendicular BC = 6m Angle BAC is θ, the angle of elevation of the sun. From the given information, we know that: Tan θ = perpendicular / base = height of pole / length of shadow = 6/2√3 = 3/√3 = √3 Tan θ = √3 Therefore θ = Tan⁻¹ √3 = 60⁰ Angle of elevation with the sun = 60⁰

22. If a flag pole of 6 metres high placed on the top of a tower throws a shadow (shadowof polo only) of 2 3 m along the ground, then find the angle of elevation with the sun

Answer»

Angle of elevation with the sun = 60⁰

Step-by-step explanation:

There is an ERROR in the question. The length of the shadow should ACTUALLY be 2√3, not 23 m.

In TRIANGLE ABC, let BC be the pole (perpendicular), then AC is the HYPOTENUSE and shadow of the pole is base AB.

Given: Base = 2√3 m

Perpendicular BC = 6m

Angle BAC is θ, the angle of elevation of the sun.

From the given information, we know that:

Tan θ = perpendicular / base = height of pole / length of shadow = 6/2√3 = 3/√3 = √3

Tan θ = √3

Therefore θ = Tan⁻¹ √3 = 60⁰

Angle of elevation with the sun = 60⁰

Please answer 21st question fastly it's urgent.

Answer»

ANSWER:

Step-by-step explanation:

1.Draw a LINE BC parallel to AD

Draw a perpendicular line BE on DF

ABCD is a parallelogram.

BC=AD=25cm

CD=AB=60cm

CF=77-CD=17cm

For Δ BCF

perimeter of triangle=(25+26+17)/2

=68/2=34

By Heron's Formula of triangle=√s(s-a)(s-b)(s-c)

=√34(34-25)(34-26)(34-17)

=204cm²

Now AREA of ΔBCF=1/2xbase X height

=1/2 BExCF204cm²

=1/2x BEx17BE

=408/17

=24cm

Area of Trapezium =1/2(AB+DF)xBE

=1/2(60+77)x24

=1644cm²

Solve equation 10/x+y +2/x-y=4 and 15/x+y-9/x-y =-2 by cross multiplicatiom method

Answer»

Step-by-step EXPLANATION:

let 1/x+y=a , 1/x-y=b

10a+2b= 4 - equation 1,

15a-9b= -2 - equation 2

eq1 ×9 = 90a+18b = 36

eq2×2 = 30a-18b = -4

______________

120A = 32

a= 32/120

a=4/15

substitute a=4/15 in eq2

15(4/15)-9b= -2

4-9b =-2

9b=4+2

9b=6

b=2/3

a=4/15 , b=2/3

x+y=4/15 - eq3

x-y=2/3 - eq4

____________

2x= 14/15

x= 7/15

substitute x= 7/15 in eq1

7/15+y = 4/15

y=4/15-7/15

y= -3/15

y= -5

hence x=7/15 , y= -5

Answer»

Step-by-step explanation:

Let the NUMBER of girls be x and boys be y.

x+y=10 -1

x= y+4 -2

Substituting 2 in 1:

y+4+y=10

2y= 6

y=3

x= 3+4=7
