Question 8

The ratio of two numbers is 5 : 4. If the sum of both the numbers is 180, then what is the smaller number among both the numbers?

Solution

Let the numbers be $$5x$$ and $$4x$$

Sum = $$5x+4x=180$$

=> $$9x=180$$

=> $$x=\frac{180}{9}=20$$

$$\therefore$$ Smaller number = $$4\times20=80$$
