Question

35 percent of a number is two times 75 percent of another number. What is the ratio between the first and the second number respectively?

Answer 1

let the 2 numbers be x and y

35%(x) = 2( 75%(y))

35x/100 = 2( 75y/100)

35x/100 = 150y/100

35x = 150y

x/y = 150/35

x:y = 30 : 7

Answer 2

Answer: Ratio of first and second number would be 30:7.

Step-by-step explanation:

Since we have given that

35% of a number is two times 75 % of another number.

Let the first number be 'x'.

Let the another number be 'y'.

According to question, it becomes,

$\dfrac{35}{100}\times x=2\times \dfrac{75}{100}\times y\\\\0.35x=1.5y\\\\\dfrac{x}{y}=\dfrac{1.5}{0.35}\\\\\dfrac{x}{y}=\dfrac{30}{7}$

Hence, ratio of first and second number would be 30:7.
