Question

Two numbers are in the ratio of 3 to 4. If the minor is 27, find the sum of both.

Answer 1

Explanation:

First we must find the missing number, for that we apply a simple rule of three:

3. 4

27 ------ x

x = 27 (4) / 3 = 36

Now we just do the sum:

27 + 36 = 63

Answer 2

Sum = 63

`\boxed{ x = 36}`

Explanation:

3 : 4

It says that the 1st part (3) is 27

27 : x (We've to find the major)

Creating a proportion:

=> 3 : 4 = 27 : x

Product of Means = Product of Extremes

=> 3 * x = 27 * 4

=> 3x = 108

Dividing both sides by 3

=> x = 36

The sum of both is 27+36 = 63
