Expert Answer:

Dear student
 
Magnification = v / u = I / O
or, v / u = 3
or, v = 3 u ........................(i)
 
we also know that,
 
1/f = 1/u + 1/v..................(ii)
 
Substituting the value of f ( = 10 cm) ans value of 'v' from equation (i) in equation (ii), we can calculate the possible object distance.
 
we hope this clarifies your doubt.
