1. Subtract 50% of a number from 120 to get 40. If this number is set as X, then 120-0.5x = 40 will get x = 1602.30, which is 6 less than 15% of a number. If this number is set as X, then 30-0.15x = 6 will get x = 1603. If a quarter of a number is 10 more than 15% of this number, then x / 4-0.15x = 10 will get x = 1004

The sum of 30% of a number and 15% of it is 153. What is the number

Let this number be X
30%x+15%x=153
45%x=153
x=153÷0.45
X=340
A: the number is 340
