Question

if 750 amounts to 885 in three years at simple interest find the rate of interest

Answer 1

885-750=135
so 750÷100=7.5
so 135÷7.5=18
so the answer is 18/3=6%

Answer 2

hi friend
here's your answer looking for

here,
Principal = 750

SI = amount - principal = 885-750=135

time = 3yrs

rate = ?

so, we know that ,

$si = \frac{p \times t \times r}{100} \\ 135 = \frac{750 \times 3 \times r}{100} \\ r = \frac{1350}{75 \times 3 } \\ r = 6\%$

so, this is your answer

hope you are satisfied with my answer
