Question

A box contains orange balls and green balls the number of green balls is 10 more than five times a number of orange balls if they’re 154 balls altogether then how many green balls and how many orange balls are there in the box

Answer 1

There are 24 orange balls and 130 green balls in the box.

Explanation:

Let orange balls be x and green balls be y.

y = 10+5x

x+y = 154

y = 154-x

Now,

y=10+5x

or, 154-x = 10+5x

or, 154-10 = 5x+x

or, 144 = 6x

so, x = 24

Now,

y = 154-x

or, y = 154-24

so, y = 130
