a parallelogram and a rhombus are equal in area.the diagonals of the rhombus are 110m and 44m. if the base of a parallelogram is 88cm, find its corresponding altitude.

Answer»

AREA of RHOMBUS = a * b/2

                            = 110 * 44/2

                            =2420 sq m

Now, Area of PARALLELOGRAM = b * H

                                       2420 = 0.88 * h

                                  THUS,   h =  2420/0.88 = 2750 sq m

Hey!!!Good Afternoon ☺Please solve the following questionRohit deposited Rs 8000 with a finance company for 3 years at an interest of 15% per annum .What is the compound interest that Rohit gets after 3 years?

Answer»

Hiii dear good afternoon here is your answer


We know that amount A at the END of n years at the rate of R% per ANNUM is given by = A = P(1+R100)n

Given:

P = RS 8,000

R = 15% p.a.

n = 3 years.

Now,

A = 8000(1+15100)3

A = 8000(115100)3

A = Rs. 12,167

And, CI = A – P = Rs 12,167 – Rs 8,000 = Rs 4,167

0.5 X + 1 upon 3is equal to 0.25 X + 7

Answer»

Hii !!



0.5 X + 1/3 = 0.25 X + 7




1.5 X + 1/3 = 0.25 X + 7



1.5 X + 1 = 3 ( 0.25 X + 7 )


1.5 X + 1 = 0.75 X + 21



1.5 X - 0.75 X = 21 - 1


0.75 X = 20



X = 20/0.75 = 4 / 0.15



X = 4 / 0.15

Rationalise the denominator 3√2/√3+√6-4√3/√6+√2+√6/√2+√3

Answer»

(3√2) /(√3+√6) = [ { (3√2) × (-√3+√6) } / {(√3+√6) × (-√3+√6)} ]                         = (- 3√6 + 3√12)/(3) = √12 - √6 = 2√3 - √6. (4√3) /(√2+√6) = [ { (4√3) × (-√2+√6) } / {(√2+√6) × (-√2+√6)} ]                         = (- 4√6 + 4√18)/(4) = √18 - √6 = 3√2 - √6.(√6) /(√3+√2) = [ { (√6) × (-√2+√3) } / {(√3 + √2) × (-√2+√3)} ]                         = (- √12 + √18)/(1) = -√12 + √18 = 3√2 - 2√3. So, (3√2) /(√3+√6)  + (4√3) /(√2+√6) + (√6) /(√3+√2)       = 2√3 - √6. + 3√2 - √6. + 3√2 - 2√3.      = 6√2 - 2√6

In a class 30% of the students play tennis only and 40% of the students play squash only. 20 students do not play any of these games and 40 play both games.Find:1-No. of students in the class2-tennis students3-Squash studentskoi help kare degs mera

Answer» SOLUTION:

\textbf{Q1: No. of <klux>STUDENTS</klux> in the class}

Let the no. of students be x

Students playing only TENNIS = 30% of x

= \frac{30}{100} \times x \\ \\ = \frac{3x}{10}

Students play SQUASH only = 40% of x

= \frac{40}{100} \times x \\ \\ = \frac{4x}{10}

Therefore,

\frac{3x}{10} + \frac{4x}{10} + 20 + 40 = x \\ \\ \frac{3x}{10} + \frac{4x}{10} - \frac{x}{1} = - 60 \\ \\ \frac{3x + 4x - 10x}{10} = - 60 \\ \\ \frac{3x}{10} = 60 \\ \\ x = \frac{60 \times 10}{3} \\ \\ x = 200 \\ \\ total \:number\:of\:students \: are = 200

\textbf{Q.2: Number of tennis students}

= \frac{3 \times 200}{10} \\ \\ = 60 \\ \\ =60 + 40 \\ \\ number\:of\:tennis\:students=100

\textbf{Q.3: Number of Squash students}

= \frac{4 \times 200}{10} \\ \\ = 80 + 40 \\ \\number\:of\:squash\: students = 120

by selling a. chair for ru 3168 anuj losses 12% find the cost prize what percent would gain or loss selling the chair for Ru 3870?

Answer»
  • SP = 3168
  • Loss = 12 %

So CP =  3168 x 100/88 = 3600

Now

Again SP = 3870 .

So

GAIN  = 3870 - 3600 = 270.

Gain % = 270/3600 x 100 % = 7.5 %

roohi travels 300 km to her home partly by train and partly by bus she takes 4 hours if she travel 60 km by train and the remaining by bus if we travel 100 KM by train and the remaining by bus seat x 10 minutes longer find the speed of the train and the bus separately

Answer»

Total distance travelled be Roohi=300
Let speed of train be x
Let speed of BUS bus be y
Travelling 60km by train and rest by bus she took 4 HOURS to cover 300km
Travelling 100km by train and rest by train she took 4 hours and 10 minutes.
Putting this relations into EQN, we get,
60/x+240/y=300
100/x+200/y=300
Rearranging the above eqns 
60y+240x=300xy→(1)
100y+200x=300xy→(2)
Divide first eqn by 60
y+4x=5xy→(3)
Divide second by 50
2y+4x=6xy→(4)
SUBTRACTING (3) from (4)
2y+4x=6xy
-y-4x=-5xy
Gives x=1km/min
=60km/hr
From eqn 

60/x+240/y=4
60/60+240/y=4
240/y=4-1
240/3=y
y=80km/hr
Speed of train is 60km/hr 
Speed of bus is 80km/hr
