Answer:

(4) 1411, 1079

Step-by-step explanation:

let the numbers be x & y respectively

a/q

6.5x/100 = 8.5y/100

=> 6.5x = 8.5y

=> 13x = 17y

or

x:y = 17:13

now,

given

x+y = 2490

but found that,

x&y are 30 unit... i.e. 17+13

hence

30 unit = 2490

1 unit = 83

so

x = 83 × 17 = 1411

y = 83 × 13 = 1079
