Question

When 30 percent of number is added to another number the second number increases to its 140 percent what is the ratio between first and second number?

Answer 1

here is the reqired answer.....

Answer 2

Ratio between first number and second number is 4:3.

• 30% of a number when added to another number it is equal to 140% of the second number.
• Let the first number be x and the second number be y.
• According to the given condition,

0.3x + y = 1.4y    (Equation 1)

• We have to find the ratio of first number to second number that is x/y.
• We solve the equation,

0.3x = 0.4y

$\frac{x}{y} = \frac{0.4}{0.3}$

$\frac{x}{y} = \frac{4}{3}$
