Question

find the rate of interst per annum
p=5200 si=975 t=18 Month
​

Answer 1

Explanation:

p=5200

si=975

t=18 Month=18/12=3/2years

$r = \frac{si \times 100}{p \times t} \\ = \frac{975 \times 100 \times 2}{5200 \times 3} \\ = 12.5\%$

Answer 2

Answer:

12.5%

Explanation:

SI = P×R×T /100

T = 18 MONTHS = 12 months = 1 year

18 months = 18 / 12 = 1.5 years

975 = 5200 × R × 1.5 / 100

R = 975× 100/5200× 1.5

R = 12.5%
