Question

the difference of two number is 15 . Half of the smaller number is greater than 1/5 of the greater number by 4. find the numbers

Answer 1

smaller number = a

greater number = b

(1/2 x a)  =   (1/5 x b) + 4

a/2 - b/5 = 4

a = 2b/5 + 8

b - 2b/5 - 8 = 15

5b - 2b = (15 + 8)5

3b = 115

b = 115/3 = 38.33

38.33 - a = 15

a = 23.33

So numbers are 38.33 and 23.33
