Question

find the amount directly using the formula A=P [1+RT/100] when principal =3200,rate=7.5p.a. simple interest and time 2.5 years.​

Answer 1

Answer:

ok as per the question to find the Amount directly using P(1+RT/100). steps to be followed are:

Step-by-step explanation:

PRINCIPAL given = 3200/-

RATE OF INTEREST = 7.5%

TIME=2.5yrs

●7.5 %= 75/10 %

2.5 yrs in fraction form is 25/10 yrs or if simplified more we get :5/2yrs

let's take out the amount now:

P(1+RT/100)=A.

3200(1+75×2.5 whole divided by 1000)

the hundred becomes thousand because we have did 75 /10 earlier so the 0 gets added to 100 and thus it becomes 1000.

now we will convert the Rate of interest into decimal forms:

75/1000=0.075

now we will put the formula :

P(1+RT) the actual formula is this which I have written here. not that in question its given just for sure to convert the RT into decimal form.

3200(1+0.075×2.5)

=>3200× 1+0.1875

=>3200×1.1875

=>3800/-

so the amount is 3800/-.
