8.	on dividing a natural number by 13 the remainder is 3 and on dividing a number by 21 the remainder is 11 if the number lies between 500 and 600 then find the number and find the remainder on dividing the number by 19
Answer» Answer: The required Number is 536 and remainder is 4. Step-by-step EXPLANATION: Let x be the number. using DIVISION algorithm we get, x = 21A + 11. Also, x = 13b + 3 Now let's find the smallest such number. 21a + 11 = 13b + 3. 21a - 13b = - 8 The smallest a and b which ensures that we get an integer is a = 12 and b = 20. Substitute in above equations and we get the smallest number to be 260. Now to get the next solution, we can take a=25 and b=41. So, the number is 536, which as required lies between 500 and 600. Now DIVIDING 536 by 19. We get remainder = 4. Therefore, The required Number is 536 and remainder is 4.

on dividing a natural number by 13 the remainder is 3 and on dividing a number by 21 the remainder is 11 if the number lies between 500 and 600 then find the number and find the remainder on dividing the number by 19

Answer»

Answer:

The required Number is 536 and remainder is 4.

Step-by-step EXPLANATION:

Let x be the number.

using DIVISION algorithm we get,

x = 21A + 11.

Also, x = 13b + 3

Now let's find the smallest such number.

21a + 11 = 13b + 3.

21a - 13b = - 8

The smallest a and b which ensures that we get an integer is a = 12 and b = 20. Substitute in above equations and we get the smallest number to be 260.

Now to get the next solution, we can take a=25 and b=41.

So, the number is 536, which as required lies between 500 and 600.

Now DIVIDING 536 by 19.

We get remainder = 4.

Therefore, The required Number is 536 and remainder is 4.

15.	if 20% of a certain quantity of work is done by A abd after that the remaining 80% of work is done by B the work will be completed in 20 days if 80% of the work is done by A and after that the remaining 20 % of tge work is done by B the work will be completed in 30 days how many days are required to complete the work if A and B work together?
Answer» LET, A TAKE 'a' days to complete 100% work. B take 'b' days to complete 100% work. I. 20% by A and 80% by B : 20% of work by A => A took a/5 days 80% of work by B => B took 4b/5 days So, (a/5) + (4b/5) = 20 => a+4b = 100 ---->(1) II. 80% by A and 20% by B : 80% of work by A => A took 4a/5 days 20% of work by B => B took b/5 days So, (4a/5) + (b/5) = 30 => 4a+b = 150 ---> (2) Solving (1) and (2), we GET , a = 100/3 days , b = 50/3 days A's one-day work = 3/100 and B's one-day work = 3/50 Thus, A and B's one-day work (combined) = 3/100 + 3/50 = 9/100 Thus they WOULD take 100/9 = 11 1/9 days to complete the work.

15.

if 20% of a certain quantity of work is done by A abd after that the remaining 80% of work is done by B the work will be completed in 20 days if 80% of the work is done by A and after that the remaining 20 % of tge work is done by B the work will be completed in 30 days how many days are required to complete the work if A and B work together?

Answer»

LET,

A TAKE 'a' days to complete 100% work.

B take 'b' days to complete 100% work.

I. 20% by A and 80% by B :

20% of work by A => A took a/5 days

80% of work by B => B took 4b/5 days

So, (a/5) + (4b/5) = 20

=> a+4b = 100 ---->(1)

II. 80% by A and 20% by B :

80% of work by A => A took 4a/5 days

20% of work by B => B took b/5 days

So, (4a/5) + (b/5) = 30

=> 4a+b = 150 ---> (2)

Solving (1) and (2), we GET ,

a = 100/3 days , b = 50/3 days

A's one-day work = 3/100 and B's one-day work = 3/50

Thus, A and B's one-day work (combined) = 3/100 + 3/50 = 9/100

Thus they WOULD take 100/9 = 11 1/9 days to complete the work.

Answer» Let the amount of money with the brother be X . This money was doubled by ELDEST sister. Now money with brother = 2x Money given to sister = 2000. Money LEFT = 2x - 2000. This amount was again doubled by second sister . Amount becomes = 4X-4000. Amount given to sister = 2000. Amount left = 4x - 6000. This is again doubled by third sister. Amount becomes = 8x - 12000. Amount given to sister = 2000. Amount left = 8x - 14000. This is equal to 5000. 8x - 14000 = 5000. x = 2375 rupees. Hope you understood my answer. If yes then plz mark me as the brainliest.

a Garrison of 120 man has provision for 30 days at the end of 5 days 5 more men joined them how many days can be sustained on the remaining provisions

Answer»

SOLUTION:

____________

Initial strength of men = 120 men

Remaining provision to LAST = 30 - 5 = 25 days

New strength of men = 120 + 5 = 125 ............... ( 5 more men join after 5 days)

Using Unitary Method (inverse relation between men and days))

Provision for 120 men COULD last = 25 days

Provision for 1 man could last for = 25 x 120 ............( inverse relation)

Provision for 125 men would last = $\frac{25 X 120}{125} = 24$

So, the required answer is 24 days
