Question

The sum of one-fourth , one -ninth , and one-third of a number is 25.find the number

Answer 1

Answer:

we need to find out the value of x

Step-by-step explanation:

x/4+x/9+x/3=25[lcm of 3,4,9=36]

so 9x+4x+12x = 25 x 36

25x/25 =36

so the number we required is 36[x=36]

Answer 2

Answer:

36

Step-by-step explanation:

Let the number be x.

Then,one-fourth of the number =x/4

         one-ninth of the number =x/9

          one-third of the number =x/3

∴ x/4 + x/9 +x/3 = 25

⇒9x +4x +12x/36 =25

⇒25x/36 = 25

⇒ x = 36/25 × 25

⇒ x = 36

Hence , the required value of the number is 36
