If 5% of x+3/10=20, then the value of x is?​

Answer 1

Hello !!

Based on logical reasoning, you can answer this question.

5% is 5/100

Now, you can use this information for you answered this question.

5x/100 + 3/10 = 20

(50x + 300)/1000 = 20

20000 = 50x + 300

-50x = 300 - 20000

-50x = -19700 (multiply for (-1))

50x = 19700

x = 19700/50

x = 394

Now, you check the result.

(5 × 394)/100 + 3/10 = 20

1970/100 + 3/10 = 20

(19700 + 300)/1000 = 20

20000/1000 = 20

20 = 20 (TRUE).

Final result : the solution for (x) is 394.

I hope I have collaborated !
