Solutions :-
Given :
Interest for 2 years = ₹ 8,352
Interest for 3 years = ₹ 8,928
Find the Interest for 1 years :-
Interest for 1 years = ₹ (8928 - 8352) = ₹ 576
Find the Interest for 2 years :-
Interest for 1 years = ₹ 576
Interest for 2 years = ₹ (576 × 2) = ₹ 1152
Find the principle :-
Principle = 8352 - Interest for 2 years
= ₹ (8352 - 1152)
= ₹ 7200
Find the rate percent :-
Rate = (100 × Interest for 2 years)/(principal × time) %
= (100 × 1152)/(7200 × 2) %
= 115200/14400 %
= 8 %
Hence,
Principle = ₹ 7200
Rate percent = 8 %
