1.	Let →a,→b and →c be three non -zero vectors such that no two of these are collinear. If the vector →a+2→b is collinear with →c and →b+3→c is collinear with →a (λ being some non -zero scalar) then →a+2→b+6→c equals
Answer» Let $\to a, \to b$ and $\to c$ be three non -zero vectors such that no two of these are collinear. If the vector $\to a + 2 \to b$ is collinear with $\to c$ and $\to b + 3 \to c$ is collinear with $\to a$ $(λ$ being some non -zero scalar) then $\to a + 2 \to b + 6 \to c$ equals
