Question

The simple interest on a certain sum for 4 years at 9% per annum is 114 more than the simple interest on the sum for 3 years at 10% per annum . find the sum​

Answer 1

Answer:

1900

step by step explanation :

let the principal P = rs X

time T = 4 years

rate of interest R = 9%

simple interest SI = SI1

and now 2nd one

2) p = rs X

T = 3years

R = 10%

SI = SI2

according to the problem given

SI1--SI2= rs 114

= ptr/100--ptr/100=114

SI = ptr/100

p/100 (tr--tr)=114

p/100 (4×9--3×10)=114

p/100 (36--30)=114

p/100×6=114

p=114×100/6

=rs.1900 is the principal (p)
