`3900 for the whole work, how should they divide the money? What value you can depict from this?

Answer 1

Answer:

Step-by-step explanation:

a 1 day work = 1/2

b 1 day work = 1/3

c 1 day work = 1/4

abc together 1 day work = 1/2 +1/3 + 1/4

= (1/12)(6+4+3)

= 13/12

abc will complete work in 12/13 days

ratio of abc 1 days work

a:b:c

=1/2 : 1/3 : 1/4

= 6 : 4 : 3 ( multiplting by 12)

let x is commin multipler

a b c income respectively

6x , 4x and 3x

total income = 6x +4x +3x = 13x

13x = 3900

x = 300

a share = 6x = 6*300= 1800

b share = 4x = 4*300 = 1200

c share = 3x = 3*300 = 900
