Step-by-step explanation:
Let komal's present age be x
Heena's present age is y
Given
X=5y---(1)
10 years later,
X+10=3(y+10)
X+10=3y+30----(2)
Substitute 1 in 2
5y+10=3y+30
5y-3y=30-10
2y=20
y=10 years
X =5(10)=50 years
THEREFORE, komal's age after 10years is
50+10=60 years

Answer:
Let the age of komal be x and that of heena be y
therefore from first condition,
x=5y
x-5y=0............ ........... (1)
from second condition,
x+10=3(y+10)
x+10=3y+30
x-3y=30-10.
x-3y=20 ...... (2)
subtracting equation one from two we get, y=10
x=2
therefore after 10 years
komals age will be=x+10=12
and that of heena=60
