Question

The sum of a number and seven times of it is equal to the product of 25.6and 12.5 what will be one fourth of that number?

Answer 1

I am writing your statement in the mathematical expression.

if

X+(7/13)X=(12.5/100)25.6,

then (1/4)X=?

If you solve this equation for x, then you will get x as 2.08

then (1/4)X is 0.52

Answer 2

Answer: 10

Step-by-step explanation:

Let the number be x

So,

x + 7x = 25.6×12.5

8x = 320

x = 320/8

x = 40

So the number is 40

Hence, 1/4th of the number = 1/4×40 = 10.
