Question

in what time will a sum of money lent at 8 1/ 3% simple interest become 4 times of itself​

Answer 1

Explanation:

let the sum = 100Rs

Simple interest=4×100

=400Rs

SI =(P×T×R)÷100

400=(100×T×8 1/3)÷100

400=(100×T×25\3)÷100

400=(2500/3×T)÷100

40000=2500/3×T

40000×3/2500=T

16×3=T

Therefore the time 48 years
