1. Natasha invests £250 in a building society account. At the end of the year her account is
credited with 2% interest. How much interest had her £250 earned in the year?
Solution: Interest = 2% of £250
= 2/100 x £250
answer = £5
2. Alan invests £140 in an account that pays r% interest. After the first year he receives £4.20 interest. What is the value of r, the rate of interest?
r/100 x £140 = £4.20
r = 100 x 4.20 / 140
= 420/140
= 3%
So the interest rate is 3%

Answer:
63, 64, 65
Step-by-step explanation:
Consecutive integers have a difference of 1 between them
let the 3 integers be n, n + 1 and n + 2 , then their sum equals 192
n + n + 1 + n + 2 = 192
3n + 3 = 192 ( subtract 3 from both sides )
3n = 189 ( divide both sides by 3 )
n = 63 ⇒ n + 1 = 64 and n + 2 = 65
the 3 integers are 63, 64 and 65
