Find the amount that the daily worker ram singh would receive if he invests rs. 8,192 for 18 months at 12 ½ % per annum, the interest being compounded half yearly.

$9826.

Step-by-step explanation:

We are asked to find the amount that the the daily worker Ram Singh would receive if he invests Rs. 8,192 for 18 months at 12 ½% per annum and the interest is being compounded half yearly.

We will use compound interest formula to solve our given problem.

, where,

,

,

,

.

Let us convert interest rate in decimal form.

As interest is compounded half-yearly, therefore, n will be 2.

1 year = 12 months,

18 months = 18/12 year = 1.5 year.

Upon substituting these values in compound interest formula we will get,

Therefore, the daily worker Ram Singh will receive $9826 after 18 months.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
