Question

four fifth of a number is 10 more than two thirds of number find the number

Answer 1

Let's assume that the number be "a".
Now according to the question.
(4/5)a = (2/3)a + 10
((4/5)-(2/3))a=10
(2/15)a=10
a=75

Answer 2

4x/5=2x/3+10
4x/5-2x/3=10
12x-10x/15=10
2x=150
X=75
so the number is75
