Question

the product of 3 brothers ages is 175. Two are twins. how old is other one. (please send the answer with steps)

Answer 1

prime factorize 175 we get 5 X 5 X 7
we know that age of 2 twins is same, so 2 same numbers are five so age of twins is 5
the only number left is 7 and hence will be the age of the other one.
Hence answer is 7

Answer 2

Concept:

Age is the the duration of a person's life or existence.

Given:

Product of ages of 3 brothers= 175

To Find:

The age of each brother

Solution:

Let the age of the twin brothers be x.

Let the age of older brother be y.

Product of ages = 175

$x*x*y = 175$

$x^{2} *y = 175$

Since, no other detail is mentioned, we will take a number that will completely divide 175., i.e. 5.

$5^{2} * y = 175\\y= \frac{175}{25} \\y = 7$

Therefore, the age of twins is 5 years and the older brother is 7 years old.
