Find the 1st number ?​

Answer 1

Step-by-step explanation:

let the first number be x

let the second number be y

30/100 * x = 40/100 *y

0.3x=0.4y------------->1

x-y=100---------------->2

x=100+y------>3

substitute 3 in 1

0.3(100+y)=0.4y

30+0.3y=0.4y

0.1y=30

y=300-------->4

substitute 4 in 3

x=400-------->5
