Answer: 348 and 355

Explanation:

Let two positive numbers are x and y

so,

when the difference is 7 then equation will become

x-y=7 Eq(1)

when product is 2439 then equation will become

x*y=2438 Eq (2)

By rearranging Equation (2)

x= 2438/y Eq(3)

Now put the value of x as in eq (3) in eq(1) to get y's value

(2438/y)-y=7

(2438-1)/y =7

2437 / y =7

2437/7 =y

y=348.14 approx 348

Put the value of y in Eq(1) for x

x-348=7

x=7+348

x=355

so the two positve numbers are 355 and 348

For Check

x-y=7

355-348=7

7=7
