Assumption: "7 2" is actually 7.2
Simple interest is simple. All you do is multiply the principal by the rate to get the yearly amount of interest. Therefore, 3900 times 7.2 is the same as $3900 x 0.072 = $280.80 per year interest. Since its over 3 years, just multiply by 3.
Therefore, you get $280.80 x 3 = $842.40 in interest.
To find 10.2 percent of a number, multiply the number by 0.102. In this instance, 0.102 x 390000 = 39780. Therefore, 10.2 percent of 390000 is equal to 39780.

2 percent of 390,000 is 7,800.
390000 - 35000 = 355000
One kilometre is equal to 1000 x 100 = 100000 centimetres. Therefore, 390000 centimetres is equal to 390000/100000 = 3.9 kilometres.
If that's 390000 square feet, it's already there. If it's something else, you need to tell us what it is.
There are 1000 m in 1 km. Therefore 390000 m / 1000 m = 390 km.
Replace the first zero of the Englise phone number with 44 e.g. 01204 390000 becomes 441204 390000
