A) Rs. 364 B) Rs. 432
C) Rs. 498 D) Rs. 554
 
Answer & Explanation Answer: B) Rs. 432

Explanation:

Here Avinash gave to Rajeev and Rajeev gave the same to Chanukya

Principal amount and Time is same but the only difference is Rate of interest.

Rajeev took @ 8% and gave it to Chanukya @ 6%

Here the difference in interest rate = 2%

2% of 5400 should be the extra amount paid by Rajeev to Avinash

Required amount = 2 x 5400 x 4100 = 432

 

Hence, Rs. 432 is the extra amount has to be paid by Rajeev to Avinash after 4 years.
