Answer:
150 is the right answer
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
