Answer 1

Answer:

Let the number be x.

Four-fifths of the number is (4/5)x

Two-thirds of the number is (2/3)x.

10 more than two-thirds of the number is (2/3)x +10.

Hence the given problem will be (4/5)x =(2/3)x +10

I.e., 4x/5 = 2x/3 +10

Multiply through out by 15 which is the LCM of 5and 3 we get

12x=10x+150

12x-10x = 150

2x = 150

x = 75

Hence the required number is 75.

Hope this is helpful for you.
