The image is located at a distance of 10.06 cm.

Explanation:

The magnification is positive in concave lens when image is virtual and erect.

Focal length of concave lens, f = -15 cm

Magnification of lens is given by :

m=\dfrac{v}{u}

0.33=\dfrac{v}{u}

v=0.33u...........(1)

Using lens formula we have :

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

\dfrac{1}{v}=\dfrac{1}{u}+\dfrac{1}{f}

\dfrac{1}{0.33u}=\dfrac{1}{u}+\dfrac{1}{(-15)}

u = -30.5 cm

Put in equation (1) as :

v=0.33\times (-30.5)

v = -10.06

So, the image is located at a distance of 10.06 cm.
