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