प्रश्न

The ratio between two quantities is 3:4. If the first number is 810, find the second number.

योग

उत्तर

Let the second number be x. According to the given ratio 3:4, we can write:

`810/x = 3/4`

To solve for x, cross-multiply the fractions:

810 × 4 = 3 × x

3240 = 3x

Now, divide both sides of the equation by 3:

`x = 3240/3 = 1080`

The second number is 1080.
