Answer 1

Answer:

Rs 2992.88

Step-by-step explanation:

Rs.8829 is divided into three parts in such a way that their amounts at 4% per annum simple interest after 5,6 and 8 years are aqual . Find the second part​

Let say Amount are 100A , 100B & 100C

100A * 4 * 5 /100  = 100B*4*6/100 = 100C*4*8/100

=> 5A = 6B = 8C =  k

=>  A : B : C ::: k/5 : k/6 : k/8

=> A : B : C :::  24k : 20k : 15k

100A + 100B + 100C = 8829

=> 2400k + 2000k + 1500k = 8829

=> 5900K = 8829

=> 2000k = (8829/5900) * 2000 = 2992.88

2nd  Part = 2992.88 Rs

Amount      Interest

3591.46      718.29

2992.88      718.29

2244.66       718.29
