Question

It seven times a number is added to 1/5th of itself, then 5/6th of the sum is equal to 30. Find the number​

Answer 1

Step-by-step explanation:

Let us consider the number be ''x''

7x + $\frac{1}{5}$ of x = sum

= 7x + $\frac{x}{5}$ = sum

= 5/6 sum = 30

= 5/6 (7x/2 + x/5) = 30

= 5/6 (35x + x / 5) = 30

= 5/6 × 36x/5 = 30

= 6x = 30

= x = 30/6

Therefore,

                  x = 5

Required Number, x = 5
