Answer 2

Answer:

ok

Step-by-step explanation:

Rs 5600 & Rs 2400 are two parts if Rs.8000 is divided in two parts such that one part be lent at 15/2℅ p.a. for 2years and the other at 8℅ p.a. for 3 Years and total interest = Rs 1416

Step-by-step explanation:

Let say first Part = Rs P

then second Part = 8000 - P Rs

First Part interest

P = P

R = 15/2 %

T = 2 Years

SI = P * (15/2) * 2 /100 = 15P/100 Rs

Second Part interest

P = 8000 - P

R = 8%

T = 3 Years

SI = (8000 - P) * 8 * 3 /100 = 1920 - 24P/100 Rs

15P/100 + 1920 - 24P/100 = 1416

=> 504 = 9P/100

=> 56 = P/100

=> P = 5600

1st Part = Rs 5600

2nd Part = 8000 - 5600 = 2400 Rs
