Related The time required for a sum of money to amount to five times itself at 16% simple interest p.a. will bea)25 yearsb)20 yearsc)15 yearsd)18 yearsCorrect answer is option 'A'. Can you explain this answer?

GIVEN:

Rate of Interest = 16%

FORMULA USED:

Simple Interest = (P × R × T)/100

CALCULATION:

Let Principal = x

Amount = 5x

Simple Interest = 5x - x=4x

Simple Interest = (P × R × T)/100

4x = (x × 16 × T)/100

T = 25 years.

Alternate method:

Principal (100) → amount (500)

So, interest = 500 - 100 = 400 @ 16%

Therefore, required time = 400/16 = 25 years

In this problem, it is given that the rate is 12 % per annum and we need to find the time in which the principal amount doubles. The total amount at the end of N years is the sum of simple interest and the principal amount. Hence, the required time is 8 years and 4 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.
