Solution:

Let sum invested for 21% = Rs. and sum invested for 35% = Rs.

(8000 − 100x)

Time period = 1 year
⇒ Simple interest =

{P×R×T}/100

According to ques,
⇒

{100x×21×1}/100

={(8000−100x)×35×1}/100

⇒

21x = (80 − x) × 35

⇒

21x= 2800 − 35x

⇒

35x + 21x = 56x = 2800

⇒

x = 2800/56 =50

∴ Interest for each part =

{100×50×21×1}/100

= Rs. 1050
