In what time does a sum of money becomes 2 times at the simple interest of 3% per annum?

Given that, the sum of money triples itself in 20 years

Show

∴ P + I = 3P

∴ I = 2P

and T = 20 years

Now simple interest I = `"PRT"/100`

∴ 2P = `("P" xx "R" xx 20)/100`

∴ R = 10

∴ Rate of interest = 10% per annum

The time period is to be calculated for the condition that the sum doubles itself i.e. for the condition

P + I = 2P

i.e. I = P

i.e. `("P" xx "R" xx "T")/100 = "P"`

∴ `(10 xx "T")/100 = 1`

∴ T = 10

∴ The sum will become double of itself in 10 years.

Or we can say this a 0.0 titi five. But seeing so we can say like if suppose a principal amount is one in tow, X and the component amount will be three multiplied by X, where n is the time off component off the interest that is given nearly so that is one year now, using all these components in the function as three X is equal to x one pillars 0.35 debated way one minute to plague way one into de now solving this equation. Biggert as three is equal toe one plus zero point zero to the five upon one to the power de Now taking the log at both side, we can get as de multiplied way log one point 0 35 is equal to log today hands he will come out as lock three divided by log 1.2 d play.

Let Principal be ‘p’

A sum of money becomes 3 times of itself,

Amount, A = 3p SI = A - p = 2p

⇒ 2p = (p × 10 × t) /100

⇒ 200/10 = t = 20 years

∴ In 20 years, a sum of money becomes 3 times of itself.

In how many years will a certain sum become

3 times itself at 25 %

per annum under simple interest?

(a) 5 (b) 8 (c) 12 (d) 6 Open in App Solution If the sum be P . Amount ( A ) = 3 × P = 3 P Simple interest ( S . I ) = A − P = 3 P − P = 2 P Let the sum (P) be x

Then, simple interest

Rate of interest Time S . I = P × R × T 100 ⇒ T = 100 × S . I P × R = 100 × 2 x x × 25 = 4 × 2 = 8 Hence, 8 years required.

Hence, the correct option is (b).

How many years does a sum of money becomes 3 times itself at 12.5% pa simple interest?

Solution : Let T years be the required time period. <br> Given that, <br> Amount `(A)=3 xx ` Principal (P) <br> `therefore P(1+(TR)/(100))=3P` <br> `implies 1+(12T)/(100)=3 implies T=(200)/(12)=16(2)/(3)` years <br> Hence, required time period`=16(2)/(3)` years.

In what time will the sum of money becomes three times?

In what time will the interest on a certain sum of money at 6 be of itself?

Given that sum of money at 6% be 5/8 of itself. Therefore, S.I = 5x / 8. T = (S.I × 100) / P × R. That is 10 years and 5 months.

How many years does a sum of money becomes 3 times itself at 12.5% pa simple interest?

Solution : Let T years be the required time period. <br> Given that, <br> Amount `(A)=3 xx ` Principal (P) <br> `therefore P(1+(TR)/(100))=3P` <br> `implies 1+(12T)/(100)=3 implies T=(200)/(12)=16(2)/(3)` years <br> Hence, required time period`=16(2)/(3)` years.
