If two numbers are in the ratio 5:3 , it means the total of the two is 8 parts and the two numbers are 5 parts and 3 parts of the total.

Then the difference between them is 2 parts of the total. Two parts are equal to 18. So one part is 9. So eight parts will then be 8*9 = 72. Then the two numbers are 5 parts = 5*9=45 and three parts 3*9 = 27.

==============

If a number is decreased by 5%, then it becomes 100 % - 5% = 95% of itself. That means 95/100 of number is 3, 800.

The number then will be equal to 3,800 * 100 /95 = 4, 000
