Answer 2

Answer:

15/2 %

Step-by-step explanation:

P = rs 5200

t = 2,1/2 yr = 5/2 yr

SI = rs 975

so , we know that

SI = prt/100

$975 = \frac{5200 \times r \times 5}{100 \times 2 } \\ 195 = \frac{5200r}{200} \\ 195 = 26r \\ 15 = 2r \\ \frac{15}{2} = r$

Therefore the required rate of interest is 15/2 % per annum.
