Question

 a number is as much less 75 than as it is more than 45. find the number

Answer 1

Thanks for asking the question.
According to the given statement:
suppose the number be ''z''
let the number y less than 75
So, 75-y= z..... eq.1
and let it be ''y'' more than 45,
z= 45+y
from eq.1 and 2, we get:
75-y=45= y
75-45= y+y
2y= 30
y= 30/2
y= 15
Now, putting the value of y in eq.1, we get:
75-y=z
y= 15
75-15= z
z= 60
And 60 is the final answer.
Hope it helps.
