How much investment is required to yield an annual income of RS. 210 at 7% per annum simple interest?

Answer»

Let \: the \: investment\: required = Rs \: P ,\\Rate \:of \: interest (R) = 7\%, \\Simple\: Interest (I) = Rs\:210 ,\\Time (T) = 1\: year

\boxed { \pink { P = \frac{ 100\times I}{TR}}}

P = \frac{ 100\times 210}{1 \times 7} \\= Rs \:3000

THEREFORE.,

How long will a man take to make a round of a circular field of radius 21 m, cycling at thespeed of 8km/h​

Answer»

Step-by-step explanation:

Formula

Circumference\ of\ a\ circle = 2\pi rCircumference of a circle=2πr

Where r is the radius of the circle .

Speed = \FRAC{Distance}{Time}Speed=TimeDistance

As given

A man take to MAKE a of a circular field of radius 21 m.cycling at the speed of 8km/h .

Put all the values in the formula

\pi =\frac{22}{7}π=722

Circumference\ of\ a\ circle = 2\times \frac{22}{7}\times 21Circumference of a circle=2×722×21

Circumference\ of\ a\ circle = 2\times 22\times 3Circumference of a circle=2×22×3

Circumference\ of\ a\ circle = 132\ mCircumference of a circle=132 m

As 1 km = 1000 m

1\ m = \frac{1}{1000}\ km1 m=10001 km

Now convert 132m into km .

132\ m = \frac{132}{1000}\ km132 m=1000132 km

                  = 0.132 km

I.e

Distance = 0.132 km

Speed = 8 km / h

Put all the values in the formula

8 = \frac{0.132}{Time}8=Time0.132

Time= \frac{0.132}{8}Time=80.132

Time = 0.0165 hr

As

1 hour = 3600 second

Now convert  0.0165 hr into seconds .

0.0165 hour = 0.0165 × 3600

                      = 59.4 seconds

Therefore the time taken by the man who cycling at the speed of 8km/h on circular field is 59.4 seconds .

hope this help you.

mark as best as your wish.

Tap A needed  40 hrs & Tap B needed 24 hrs to fill the SWIMMING pool

Step-by-step explanation:

Both Taps can fill swimming pool in 15 hrs

=> Both taps can fill in 1 hr =  1/15

Both taps can fill in 12 hr = 12/15  = 4/5

swimming pool Remaining to filled  = 1 - 4/5 = 1/5

Tap A fill in 8 hrs  = 1/5

=> Tap A fill in 1 hr = 1/40

=>  Tap A can fill swimming pool  in 40 hrs

tap B can fill swimming pool in 1 hr  = 1/15  - 1/40

= (8 - 3)/120

= 5/120

= 1/24

Tap B can fill swimming pool  in 24 hrs

Tap A needed  40 hrs & Tap B needed 24 hrs to fill the swimming pool

Significance of kleins construction​

Answer»

Answer:

We have already DISCUSSED that the velocity diagram for given configuration is a triangle OCP as shown in Fig. If this triangle is rotated through 90°, it will be a triangle oc1 p1, in which oc1 represents VCO (i.e. velocity of C with respect to O or velocity of crank pin C) and is parallel to OC, op1 represents VPO (i.e. velocity of P with respect to O or velocity of cross-head or piston P) and is perpendicular to OP, and c1p1 represents VPC (i.e. velocity of P with respect to C) and is parallel to CP. A little CONSIDERATION will show that the triangles oc1p1 and OCM are similar. Therefore,Thus, we see that by drawing the Klein’s velocity diagram, the velocities of various points may be obtained without drawing a separate velocity diagram. Klien’s acceleration diagram: The Klien’s acceleration diagram is drawn as discussed below: 1. First of all, draw a CIRCLE with C as centre and CM as radius. 2. Draw another circle with PC as diameter. Let this circle intersect the previous circle at K and L. 3. Join KL and produce it to intersect PO at N. Let KL intersect PC at Q. This forms the quadrilateral CQNO, which is known as Klien’s acceleration diagram. We have already discussed that the acceleration diagram for the given configuration is as shown in Fig. We know that (i) o'c' represents CO ar (i.e. radial component of the acceleration of crank pin C with respect to O ) and is parallel to CO; (ii) c'x represents PC ar (i.e. radial component of the acceleration of crosshead or piston P with respect to crank pin C) and is parallel to CP or CQ; (iii) xp' represents PC at (i.e. tangential component of the acceleration of P with respect to C ) and is parallel to QN (because QN is perpendicular to CQ); and (iv) o'p' represents aPO (i.e. acceleration of P with respect to O or the acceleration of piston P) and is parallel to PO or NO. A little consideration will show that the quadrilateral o'c'x p' is similar to quadrilateral CQNO .

The perimeter of a square filed is 8km. Find its area in hectares.

Answer»

Answer:

Step-by-step explanation:

Solution :-

Perimeter of the square FIELD = 8 km

SIDE of the square = Perimeter/4

⇒ 8/4

⇒ Side of the square = 2 km

So, length of each side of the square is 2 km 

Area of square = Side*Side

⇒ 2 km × 2 km

= 4 sq km

As we KNOW that 1 sq km = 100 hectares

So, 4 km = 400 hectares

Hence, the area of the square field is 400 hectares.

Hope this helped!!!!!

If for an AP,d=5,then t18-t13=?a)5 (b) 20 (c) 25 (d) 30​

Answer»

Answer:

(C) 25

Step-by-step explanation:

LET, common difference = d = 5,

FIRST TERM = a = a,

and, number of the term = n

Tn = a+(n-1)d

T18 = a+(18-1)5

T18 = a+(17)5

T18 = a+85

Tn = a+(n-1)d

T13 = a+(13-1)5

T13 = a+(12)5

T13 = a+60

T18 - T13

= (a+85)-(a+60)

= a+85-a-60

= 85-60

= 25

If the annual increase in population of a town be 5% and present population be 22050,what was the population 2 years ago​

Answer»

(a) A= p(1+r/100)t

44100=p(1+5/100)2

44100=p(105/100)2

44100=p*105/100*105/100

44100*100*100=p*105*105

p=(44100*100*100)/105*105

p=40000

Then, POPULATION of a town 2 YEARS ago is 40000.

Population after 1 YEAR,

A=p(1+r/100)t

A=44100(1+5/100)1

A=44100*105/100

A=46,305

So, the population after 1 year is 46,305.
