When I double my number add 4 and then subtract my number and subtract three I get my number plus one what is my number?
Lady bird [3.3K]
2 because once you double it, it becomes 4. Once you add 4, you get 8. When you subtract your number, which is 2, you get 6. Then when you subtract 3, you get 3. 3 is your number (2) plus 1

Rich also has £400 pounds invest 3% compound interest . How many years does he need to invest the money to get at least £475
zepelin [54]

Answer: 6 years

Step-by-step explanation:

Formula to calculate compound amount: A=P(1+r)^t, where P= Principal , r=rate of interest, t= time

Given: P = £400, r = 3% = 0.03 , A= 475

Required equation: 400(1+0.03)^t\geq475

400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875

Taking log on both sides , we get

t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6

Hence, he needs to invest the money for 6 years to get atleast £475.
