16.	a joint family in a town has a grandmother five children and two grandchildren. in how many ways can the seating arrangement be made such that the grandchildren occupy both the seats at the end and the grandmother sits with her children on either side of her?
Answer» The question MACHINE Lendi to you but trust me the solution is very short. Latest resume that there are eight chairs. The chairs at the extreme ends are occupied by the grandchildren according to the question. So the number of chairs remaining is equal to 6. It is clearly MENTIONED in the question that the grand mother has to SIT with her children on either SIDE. Because of this condition we cannot make the grandmother sit right next to any of the Grand childrens. Therefore number of chairs available for grandmother is equal to 4. Now from those 4 chairs grandmother will be sitting at any one chair. Which means the remaining 5 chairs are free for the five childrens. So it is clear that the grandmother and the children can sit in 4 x 5 = 20 ways. Now the grandchildren at the extreme ends can sit in two ways by exchanging the positions. i.e. 20 x 2 = 40 ways Therefore, in 40 ways can the seating arrangement be made such that the grandchildren occupy both the seats at the end and the grandmother sits with her children on either side of her.

Answer»

The question MACHINE Lendi to you but trust me the solution is very short.

Latest resume that there are eight chairs. The chairs at the extreme ends are occupied by the grandchildren according to the question.

So the number of chairs remaining is equal to 6. It is clearly MENTIONED in the question that the grand mother has to SIT with her children on either SIDE.

Because of this condition we cannot make the grandmother sit right next to any of the Grand childrens.

Therefore number of chairs available for grandmother is equal to 4.

Now from those 4 chairs grandmother will be sitting at any one chair. Which means the remaining 5 chairs are free for the five childrens.

So it is clear that the grandmother and the children can sit in 4 x 5 = 20 ways.

Now the grandchildren at the extreme ends can sit in two ways by exchanging the positions. i.e. 20 x 2 = 40 ways

Therefore, in 40 ways can the seating arrangement be made such that the grandchildren occupy both the seats at the end and the grandmother sits with her children on either side of her.

17.	Two numbers are 20%&50% more than the rhird number theratio of two numbers is
Answer» The RATIO is 2: 5 Let's TAKE the third number as 'X' then we have, 20% of x = 20/100 * x =20x/100 50% of x = 50/100 x = 50x/100 Now we have, 20x/100 : 50x/100 = 20x/100 / 50x/100 = 20x/100 100/50x = 2000x/5000x =2/5 =2:5

17.

Two numbers are 20%&50% more than the rhird number theratio of two numbers is

Answer»

The RATIO is 2: 5

Let's TAKE the third number as 'X'

then we have,

20% of x = 20/100 * x

=20x/100

50% of x = 50/100 *x

= 50x/100

Now we have,

20x/100 : 50x/100

= 20x/100 / 50x/100

= 20x/100 * 100/50x

= 2000x/5000x

=2/5

=2:5

23.

after giving discount of 20%on printed price a pant is sold in rupees 560 find the printed price of pant

Answer»

GIVEN,

D% = 20% ON MP

SP = Rs. 560

MP = ?

WE KNOW THAT,

SP = MP - MP *(D%/100) =(1 - (D%/100))* MP

560 = (1 - (20/100)) * MP

560 = (80/100) * MP

MP = (560 * 100)/80

MP = Rs. 700

Please let me know if the answer is right.

46.

The no. of arbitrary constant in the general solution of a differential equation of 3rd order is

Answer»

ANSWER:

The number of arbitrary constants in the general solution of a differential equation is 3

Step-by-step explanation:

In this question,

Let y''' = 1

On INTEGRATING we get,

y'' = X + A where A is the constant

Now , again Integrating we get,

y' = $\frac{x^{2}}{2}\ +\ A\ +\ B$ where A and B are constant.

Integrating again,

y = $\frac{x^{3}}{6}\ +\ A\ +\ B\ +\ C$ Where A, B, and C are constants

Therefore, Number of Constants = 3

HENCE, Number of arbitrary constants in a general solution of a differential equation is 3
