Answer 1

so a income=6000 10/100x=600

Answer 2

or else 90x/100=600

Answer 3

so x=2000 then c should be 10000

Answer 4

a spends 10% of saving which has ratio 1 so for 30 % saving

Answer 5

so spending of c is 7000?

Answer 6

lets work A first :
savings = 600 = 10% of his income
so, income = 6000, right ?

Answer 7

yes

Answer 8

next,
their savings are in the ratio 1 : 2 : 3
since A has a saving of 600, that means C must have a saving of 3*600 = 1800, right ?

Answer 9

yes i have that problem

Answer 10

next, whats the income of C ?

Answer 11

so 8200

Answer 12

8200 he spends,10000 income

Answer 13

incomes of A, B and C are in the ratio 3 : 4 : 5

since A has an income of 6000, that means C must have an income of 6000*5/3 = 10.000

Answer 14

so his spendings = 10,000 - 1800 = 8200
