Question

The sum of one half one third and one fourth of a number exceeds the number it self by10

Answer 1

let the number be x
then according to the question
$\frac{x}{2} + \frac{x}{3} + \frac{x}{4} = x + 10 \\ \frac{13x}{12} = 10 \\ x = \frac{120}{13}$

Answer 2

1/2*3+1/4x=10

3/2+x/4=10

3+2x=10

2x=10-3

2x=7

X=7/2

X=3.5
