One fourth of one number is 5 times of another . The sum of two number is 210 . Find the number.

Answer»

Lets the first number be x and another number be y.

According to the question:

\(\frac{1}{4} x = 5y\)

x = 20y

and \(\frac{x}{y} = \frac{20}{1}\)

x : y = 20 : 1

then x + y = 21

x = \(\frac{20}{21} \times 210\)

x = 20 x 10

x = 200

and y = \(\frac{1}{21} \times 210\)

y = 1 x 10

y = 10

Hence, first number is 200 and another number is 10.
