Answer 1

let the first part be x.

second part will be 19400-x.

S.I. for first part = x×5×8/100= 2x/5

S.I. for second part = (19400-x)×9×4/100= 174600-9x/25

Now,

2x/5÷174600-9x/25= 3/7 [Given]

=> 10x/174600-9x= 3/7

=> 70x = 523800-27x

=> 97x = 523800

=> x= 5400

So, first part= Rs 5400

second part= Rs 14000
