Question

Two numbers are in ratio 5:7. Their difference is 10, find the numbers.
​

Answer 1

Answer:

answer is down

Step-by-step explanation:

Let the numbers be x and x+10 (since the difference of the two numbers is 10).

Now, we can say that, (x+10)/x=5/7 (since the ratio of the two numbers is 5:7)

or, (x+10)*7=5*x (cross multiplication)

or, 7*x+70=5*x

or, 7*x-5*x=-70

or, 2*x=-70

or, x=-35 (dividing both sides of the equation by 2)

So, the numbers are x=-35 and x+10=-25
