Question

calculate the si unit on ₹8000 for 2½ years at 4½% p.a​

Answer 1

Answer:

900

Step-by-step explanation:

total Interest = 4.5%×2.5 = 11.25%

100% = 8000

1% = 80

11.25% = 80×11.25 = 900 [Ans]

Answer 2

here is your answer:

$princpal = rs.8000 \\ rate = 4 \frac{1}{2} \% = \frac{9}{2}\% \\ time = 2 \frac{1}{2}years = \frac{5}{2}years \\ therefore, \: s.i = \frac{p \times r \times t}{100} \\ = \frac{8000 \times 9 \times 5}{100 \times 2 \times 2} = rs.(20 \times 9 \times 5) \\ = rs.900$
