5000 rupees 10% compound interest who many years it will become 6655

Answer»

Given, 

       PRINCIPAL = Rs 5000

       Amount=    Rs 6655

       Rate %   =    10 %

       Conversion period=n= ? 

  So ,  6655= 5000(1+ 10/100) n             

          6655 / 5000= (11/10) n

         1331/1000 = (11/10)n

         113/103    =  11n / 10 n

So n= 3 as 11 3 = 1331

Thus in 3 years a SUM of Rs 5000 will become Rs 6655 @ 10% p.a. COMPOUNDED anually

Two adjacent side of a parallelogram are in the ratio 3:2 the perimeter of the parellogram is 72 cm find the length of each of its sides

Answer»

Hi...☺

Here is your answer...✌

GIVEN THAT,

TWO adjacent side of a parallelogram are in the ratio 3:2

Let the common multiple be x

Then Adjacent sides are 3x and 2X

We know that,

Opposite ANGLES of parallelogram are equal

Therefore,

Other two sides are 3x and 2x

Now,

Also given that

Perimeter = 72 cm

Sum of all sides = 72 cm

3x + 2x + 3x + 2x = 72

10x = 72

x = 72/10

x = 7.2 cm

=> 3x = 3×7.2 = 21.6 cm
=> 2x = 2×7.2 = 14.4 cm

HENCE,

LENGTH of sides of given parallelogram are

21.6 cm , 14.4 cm , 21.6 cm , 14 .4 cm

Expected value of the residual error sum of squares is variance

Answer»

In statistics, the residual sum of squares (RSS), also known as the sum of squared residuals (SSR) or the sum of squared errors of prediction (SSE), is the sum of the squaresof residuals (deviations predicted from actual empirical values of DATA). It is a measure of the discrepancy between the data and an estimation model. A small RSS indicates a tight fit of the model to the data. It is used as an optimality criterion in parameter selection and model selection.

In general, total sum of squares = explained sum of squares + residual sum of squares. For a proof of this in the MULTIVARIATE ordinary LEAST squares (OLS) case, SEE partitioning in the general

On invariant analysis and conservation laws for degenerate coupled multi-KdV equations for.

Answer»

The environment degenerate coupled multi-KdV equations for coupled multiplicity l=3 are studied. The equations also known as three fields Kaup-Boussinesq equations are considered for invariant ANALYSIS and conservation laws. The classical Lie's symmetry method is used to ANALYZE the symmetries of equations. BASED on Killing's form which is invariant of adjoint action, the full classification for Lie algebra is presented. Further, one-dimensional optimal group classification is used to obtain invariant solutions. Besides this, USING general THEOREM proved by Ibragimov we find several nonlocal conservation laws for these equations. The conserved currents obtained in this work can be useful for the better understanding of some physical phenomena modeled by the underlying equations.

a sum of Rs. 4558 os divided among arun, santhosh and hari such that arun receives 20% more than hari, and hari receives 25% less than santhosh. find arun's share.

Answer»

Let amount RECEIVED by Santosh be 100x, so we have

Amt of Santosh = 100x

Amt of Hari = (0.75) 100x = 75x

Amt of ARUN = (1.2) 75x = 90X

Total amt = 4558

So we have,

100x + 75x + 90x = 4558

265x = 4558

x = 17.2

So Arun's share = 90x = 90 (17.2) = 1548

20 men can cut 30 trees in 4 hours. if 4 men leave then how many trees will be cut in 6 hours

Answer»

As in 4 hours , 20 men can cut 30 trees.

So, in 1 HOUR , 20 men can cut 30 trees / 4.

So, in 6 hours, 20 men can cut 30 * 6 trees / 4 = 45 trees.

If 4 men left the WORK so rest people  = 20 - 4 = 16.

Now, 20 men can cut 45 trees in 6 hours.

So, 1 man can cut 45 trees / 20 in 6 hours.

And ,16 men can cut 45 * 16 trees / 20 =  36 trees in 6 hours .

The ANSWER will be 36.

2/5 of the students of a class of 50 like mangoes, whereas 1/5 of them like apple and rest like banana. find the fraction of the total number of students like bananas

Answer»

Answer:

2/5 of the STUDENTS like bananas

Step-by-step explanation:

TOTAL number of students in the class = 50

Number of students who like MANGOES = (2/5) of 50

                                                              = (2/5) x 50

                                                              = 20 students

Number of students who like apple = (1/5) of 50

                                         = (1/5) x 50

                                                       = 10 students

Number of students who like bananas = (Total number of students) — (Number of students who like mangoes + Number of students who like apples)

                                                            = 50 — (20 + 10)

                                                            = 20 students

So, 2/5 students among 50 students like bananas.
