50% of a number when added to 50 is equal to the number. The number is

• A. 1000
• B. 50
• C. 150
• D. 100

Answer 1

Answer:

D. 100

Solution:

50% of a number is added to 50 = the number

Let the number be 100x

50 % of a number is $=\frac{50}{100}\times{100x}$

$=50x$

$50x+50=100x$

$50x=50$

$X=1$

The number is $= 100x=100\times{1}=100.$
