Answer:

8. let the amount earned by a, b, and c is 3x, 5x and 7x

so according to question :-

30000 = 3x+5x+7x

30000 = 15x

30000/15 = x

2000 = x

now

5x= 5*2000 = 10000

and 7x = 7*2000 = 14000

so

14000-2000 = 12000

Answer:

9th answer 840 8th answer 4000

Step-by-step explanation:

because 1+4+7=12

spent 1440

so 1440divided by 12 = 840

hence it is proved

because 3+5+7=15

profit 30000

so 30000 divided by 15=2000

2000is multiplied by 5 10000

2000is multiplied by 7 14000

so 14000-10000

=4000
