Answer 1

Let the tenth digit be x.

So 4x + x + 3x = 16

8x = 16

x = 2

Therefore,

One's = 6

Ten's = 2

Hundred's = 8

The Number is 826

Answer 2

Step-by-step explanation:

concave mirror converges light to a focal point. For lenses, light converges to a point for a convex lens. Hence a convex lens or a converging lens converges the light at a single point and its focal length is positive.
