Umar invested RM50,000 in a bank with simple interest rate is 20% per annum, find the number of years required if Umar wants the amount in the account to become RM240,000.

1 answer

To find the number of years required, we can use the formula for simple interest:

I = P * r * t

Where:
I is the interest earned,
P is the principal (initial amount),
r is the interest rate, and
t is the time in years.

In this case, Umar wants the amount in the account (A) to become RM240,000. So, the interest earned (I) would be A - P. Substituting the values into the formula, we have:

A - P = P * r * t

240,000 - 50,000 = 50,000 * 0.2 * t

190,000 = 10,000t

Dividing both sides by 10,000, we get:

t = 190,000 / 10,000

t = 19

Therefore, Umar would need 19 years for the amount in the account to become RM240,000.
