Question 154

42 per cent of first number is 56 per cent of the second number. What is the respective ratio of the first number to the second number ?

Solution

Let the numbers be $$100x$$ and $$100y$$

We need to find = $$\frac{100x}{100y} = \frac{x}{y} = ?$$

Acc to ques,

=> $$\frac{42}{100} * 100x = \frac{56}{100} * 100y$$

=> $$42x = 56y$$

=> $$\frac{x}{y} = \frac{56}{42} = \frac{4}{3}$$

=> $$x : y = 4 : 3$$
