Step-by-step explanation:
hey here is your answer
pls mark it as brainliest
so let the present age of shobha's mother be x years and that of shobha be y years
so according to first condition
x=6y (1)
according to the second condition
y+5=1/3x
ie 3(y+5)=x
ie x=3y+15 (2)
so squaring both equations
we get
3y+15=6y
ie 3y=15
so this then
y=5
substituting value of y in any of two equations
we get
x=30
thus present age of shobha's mother is 30 years and that of shobha is 5 years
