Let the age of shivani be x and shashi be y
According to the question ,
(x-5)= 3(y-5)........¡
(x+10)=2(y+10)......¡¡
now ¡ = x-5=3y-15......¡¡¡
¡¡= x+10=2y+20.......¡v
Now ¡¡¡-¡v-
-15=y-35
=>y=-15+35
=>y=20
Now putting y=20 in ¡¡¡ we get,
x-5=3×20-15
=>x-5=60-15
=>x-5=45
=>x=50
Therefore ,
Shivani is 50 years old and Shashi is 20 years old
