Respuesta :
3x + 7x = 10x = 7000 and x = 700 so 3(700) and 7(700) so it’s £2100:£4900
Answer: The required divided parts are £2100 and £4900.
Step-by-step explanation: We are given to divide £7000 in the ratio 3 : 7.
Let the required parts be 3x and 7x.
Then, according to the given information, we must have
[tex]3x+7x=7000\\\\\Rightarrow 10x=7000\\\\\Rightarrow x=\dfrac{7000}{10}\\\\\Rightarrow x=700.[/tex]
Therefore, the divided parts are
[tex]p_1=3\times700=2100,\\\\p_2=7\times700=4900.[/tex]
Thus, the required divided parts are £2100 and £4900.
