Question

If $40$%of a number is equal to two-third of another number, what is the ratio of first number to the second numbers?

• A. 2:5
• B. 3:7
• C. 5:3
• D. 7:3

Answer 1

The correct option is C 5:3

$(l-m)(lm+l+x^2)=0$

Let the number be $x_{1}y$

Given :- $40\%$ of $\left(x\right)=\frac{2}{3}$ of $\left(y\right)$

to find :-$\frac{x}{y}=?$

$\frac{40}{100}\times x=\frac{2}{3}\times y$

$\frac{x}{y}=\frac{2}{3}\times \frac{100}{40}$

$\Rightarrow \frac{x}{y}=\frac{5}{3}$
