Answer:
NO
Step-by-step explanation:
NO it is not possible to find their present age.
first let the age of 1st friend be x and 2nd friend be y.
Now sum of their ages ,
=> x+y = 20. --------- (1)
Now age of 1st 4 years ago = x-4
Age of 2nd 4 years ago = y-4
Now according to the question,
=> (x-4) × (y-4) = 48
=> xy - 4x - 4y + 16 = 48
=> xy -4x-4y = 32
=> xy -4 (x+y) = 32
=> xy - 4 × 20 = 32 (from equation 1)
=> xy -80 = 32
=> xy = 112.
Here we know that ages can only be in positive integers.
Thatswhy here we got a condition that the product of two integers is 112 and their sum is 20. And no such pair of integers exist.
HOPE THIS WILL HELP YOU
