Mr. Smith is 81 years older than his grandson, Victor. In 3 years, Mr. Smith will be four times as old as Victor. How old is Vic

puteri [66]

<h3>Answer :- </h3>

24 years

<h3>Solution :- </h3>

Let the age of victor be X .
and, the age of Mr.Smith be = 81 + x

♧ So, after 3 years = x+81 +3

81 + 3 + x = 4 ( x + 3 )
84 + x = 4x + 12

♧ now grouping the variables and constants together we get,

4x-x=84-12
3x = 72
x = 72/3
x = 24

♧ Thus, Victor's present age is 24 yrs.

Paladinen [302]

Answer:

The number of doctors recommended flash toothpaste 800.

Step-by-step explanation:

Given:

A magazine ad states that 4 out of 7 doctors recommend Flash toothpaste.

Now, to find the numbers of doctors recommended flash toothpaste if 1400 doctors were surveyed.

Let the number of doctors recommended be $x$ .

And the total number of doctors surveyed were 1400.

So, as given 4 out of 7 doctors recommend flash toothpaste.

So, 4 equivalent to 7 = $\frac{4}{7}$ .

And, $x$ equivalent to 1400 = $\frac{x}{1400}$ .

Thus, we set the proportion and solve by cross multiplication method:

$\frac{4}{7} =\frac{x}{1400}$

By cross multiplying we get:

$5600=7x$

Dividing both sides by 7 we get:

$800=x$

$x=800.$

Therefore, the number of doctors recommended flash toothpaste 800.
