Answer 1

Percentage,

We have

₹3600 divided in such way that one of it's part when interested in 9% per annum and other part 10%per annum results in ₹333 profit annum.

Let one part as ₹x which is interested in 9%
so the other part will be ₹(3600 - x), let this amount interested in 10% per annum.

So,

$x \times \frac{9}{100} + \frac{(3600 - x)10}{100} = 333$

=> 9x/100 + (36000 - 10x)/100 = 333

=> (9x + 36000 - 10x)/100 = 333

=> (36000 - x)/ 100

=> 36000 - x = 33300

=> - x = 33300 - 36000

=> - x = - 2700

=> x = 2700

So, ₹2700 is interested in 9% per annum

So ₹(3600 - 2700) = ₹900 is interested in 10% per annum.

That's it
Hope it helped (≧∇≦)b
