Given : 2605 रु० की धनराशि एक निश्चित दर पर 4 वर्षों में 2938 रु० हो |
To Find : यदि दर 25% अधिक हो तो वह धनराशि कितने रु० हो जायेगी
Solution:
SI
SI = P * R * T /100
SI = 2938 - 2605 = 333
P = 2605
R = ?
T = 4
333 = 2605 * R * 4 /100
=> R = 3.1957
25 % अधिक = 3.1957 (1 + 25/100) = 4
SI = 2605 * 4 * 4 /100
=> SI = 416.8
A =2605 +416.8 = 3,021.8 Rs
Using CI
2938 = 2605(1 + R/100)⁴
=> 1 + R/100 = 1.0305
=> R = 3.05
25 % अधिक = 3.05(1 + 0.25) = 3.816
A = 2605(1 + 3.816/100)⁴
A = 3,026
