if 3 divide a profit of rs 72,000 at end of the year according to the ratio of 2:3:4 of their investment how much did they receive

Step-by-step explanation:

Hey, there!!

See explanation in picture.

They receive 16000, 24000 and 32000 as per the ratios 2:3:4.

let x be a common factor,

Then,

2x+3x+4x =72000

sum them,

9x= 72000

x = 72000/9

=8000

Therefore, x= Rs. 8000.

2x= 8000×2 = Rs.16000

3x= 3×8000= Rs.24000

4x= 4×8000= Rs. 32000

You just need to put common factor on the ratios and then sum up them to get the value.

Hope it helps..

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

answer: 1+1

step-by-step explanation: 1+1 is at least 2
