Lens Formula, ​$$1v1$$−$$1$$−$$1=10.5$$​⇒$$v1=1m$$   Now, $$I1$$ will act like object for plane mirror.​So, $$I2$$  will be formed $$1m$$ behind the mirror. ​Now, $$I2$$ will act like object for convex lens.Lens formula,           ​ $$1v3$$−$$1$$−$$3=10.5$$​⇒$$v3=35mSo$$, real image $$I3$$ is formed at $$0.6$$ m on left of lens or $$2.6m$$ from mirror.
