Question

On decroasing a number 18% it become 697 find original number

Answer 1

Answer:

850

Step-by-step explanation:

Consider the original number as x

Here

New number = (1−18/100) of original number

Substituting the values

697=(1−18/100)×x  

Taking LCM

697=[(100−18)/100]×x  

By further calculation

697=82/100×x

So we get

x=(697×100)/82

x=(697×50)/41

By further simplification

x=17×50

x=850

Therefore, the original number is 850.
