​

Answer 1

Answer:

150 is the right answer

Answer 2

Step-by-step explanation:

Let the number be x

According to the question,

75% of x + 75 = x

=> X × 75/100 + 75 = X

= 75x/100 + 75 = x

= 75 = x - 75x/100

= 75 = (100x - 75x)/100

= 75 = 25x/100

= 75 × 100 = 25x

= x = 75 × 100/25

= x = 3 × 100

= x = 300

So, the number is 300

Check :

300 × 75% = 225

225 + 75 = 300
