The maturity value of a 30-day loan of $650 is $660. What is the annual simple interest rate (in percent) on this loan? Round to the nearest tenth of a percent. Use 360 days in 1 year. (Enter a number.)

the interest rate is 18.7%

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

P = 650

I = 660 - 650 = $10

T = 30 days. Converting to years,

T = 30/365 = 0.08219

10 = (650 × R × 0.08219)/100 = 0.5342R

R = 10/0.534 = 18.7% to the nearest tenth of a percent.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

ratio is 2 : 9

the answer is three

13.5 : 3
