(D) 400​

Answer 1

Answer:

I can explain in english and sorry for your inconvenience.

Step-by-step explanation:

Let the first number be x , so its 45% wilp be = to 45x/100

15% of 450 = 450 × 15/100 =67.5

30% of 600 = 600 × 30/100 =180

By given condition ,

45x/100 + 67.5 = 180, so

9x/20 = 112.5 , so

x = 112.5 × 20/9 , so

x = 250.

Therefore the number is 250.
