Question

If 10 added to the double of a number is 60, then find three-fifth of that number.​

Answer 1

Answer:

Let the number be x.

10 + 2x = 60

2x = 60 - 10

2x = 50

x = 50/2

x = 25

The number is 25.

Now, the three-fifth of the number,

3/5 of x

= 3/5 of 25

= 3/5 × 25

= 3 × 5

= 15

Therefore, the three-fifth of the number is 15.

Answer 2
