Answer 1

Answer:

Step-by-step explanation:

let first number = x

second number = y

According to question,

x+y = 1230 ......(i)

20% of x = 20x / 100 = x/5

50 % of y = 50y / 100 = y/2

x/5 = y/2

2x = 5y

x = 5y / 2

substituting value of x in (i)

5y / 2 + y = 1230

7y / 2 = 1230

7y = 1230 * 2

7y = 2460

y = 351 .42

substituting value of y in (i)

351 .42+ x = 1230

x = 1230 - 351.42

x = 878.8

numbers are 351.42 and 878.8
