plz write questions properly
Answer:
Sujal's present age = 8 years
Ranu's present age = 24 years
Step-by-step explanation:
Let Ranu's age be 'r'
Let Sujal's age be 's'
So,
According to the question, r = 3s ______(1)
(r+4) + (s+4) = 40 ______(2)
3s + 4 + s + 4 = 40 _____(put value
from
equation (1) to
equation (2) )
4s + 8 = 40
4s = 40 - 8
4s = 32
s = 32/4
s = 8 --------Present age of Sujal.
Put value of 's' in (1)
r = 3s
r = 3 *8
r = 24 ----------Present age of Ranu.
