Question

2. In what time will the Simple Interest on 400 at 10% per annum be the same as the
Simple Interest on 1,000 for four years at 4% per annum?​

Answer 1

Answer:

4 years

Step-by-step explanation:

S.i on 1000 in 4 years at 4 % rate is

=> S.i = P×R×T/100

=> 1000×16/100

=> 160 RS

now we wants si 160 RS on 400 at rate of 10 % so

=> 160 = 400×10×t/100

=> 16000/4000 = t

t = 4 years
