Answer 2

Answer:

no. of people= 4

amount received by each= 20

Step-by-step explanation:

let the no. of people be y

let the amount received by each be x

now total amount will be xy,

ATQ,

first equation,

(y+4)(x-10)= xy

xy + 4x -10y -40 = xy

4x - 10y = 40

second equation,

(y-2)(x+20)= xy

xy - 2x + 20y - 40 = xy

-2x + 20y = 40

using elimination method,

on adding the two equations,

4x - 10y = 40

(-2x +20y = 40)*2

-10y + 40y = 40+80

30y= 120

y= 4

putting the value of y in equation second,

-2x + 20(4) = 40

-2x + 80 = 40

-2x = -40

2x = 40

x = 20
