Answer 2

The greatest number is 150.21

Step-by-step explanation:

Let the first number be x and second number be y

We are given that 12% of the first number is equal to 25% of the second number

So, 12% of x = 25% of y

$\frac{12}{100}x=\frac{25}{100}y$

$x=\frac{25}{100}y \times \frac{100}{12}$

x=2.08y

The difference between the two numbers is 78

x-y=78

2.08y-y=78

1.08y = 78

$y=\frac{78}{1.08}$

y=72.22

x=2.08y=2.08(72.22)=150.21

Hence The greatest number is 150.21
