Solution:

Let sum invested for 25% = Rs.

100x

and sum invested for 13% = Rs.

(15200 − 100x)

Time period = 1 year
⇒ Simple interest =

{P×R×T}/100

According to ques,
⇒

{100x×25×1 }/100 ={(15200−100x)×13×1}/ 100

⇒

25x = (152 − x) × 13

⇒

25x = 1976 − 13x

⇒

25x + 13x = 38x = 1976

⇒

x = 1976/38 =52

∴ interst for each part =

{100×52×25×1}/100

= Rs. 1300
