Sagot :
In this question the options are not given clearly but the value of x in terms of y can be written as
[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]
According to the given situation in the question
Andrew calculates that 40% of 50% of x = 20% of 30% of y
Given that x ≠ 0
The given condition can be formulated in the form of equation (1) as follows
[tex]\rm 40\% \times 50\% \times x = 20\% \times 30\%\times y ........(1)\\[/tex]
Equation (1) can be further solved to get
[tex]\rm \dfrac{40}{100} \times \dfrac{50}{100} \times x = \dfrac{20}{100}\times \dfrac{30}{100}\times y[/tex]
[tex]\rm 2/5\times (1/2)\times x = (3/50)\times y[/tex]
[tex]\rm x /5 = 3/50 \times y \\x = \dfrac{3y}{10}[/tex]
In this question the options are not given clearly but the value of x in terms of y can be written as
[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]
