Lets count:
All the corners will have 3 faces painted, there are total of 8 corners.
Cubes at the edge(except corners) will have 2 faces painted, there will a one such cube per edge, there are a total of 12 edges, thus 12 cubes will have 2 faces painted.
You can imagine one cube formed by exact center of a face will have only one face painted, there are a total of 6 faces in a cube, thus 6 such cubes will exists.

So total number of cubes with at least one face painted = 8 + 12 + 6 = 26

We can even confirm our calculation by counting the number of painted faces
Number of painted faces = 8*3 + 12*2 + 6 = 24 + 24 + 6 = 54 = 9*6(Each face of the original 3x3x3 cube is cut into 9 pieces.

16 men can finish a job in 12 days.

1 man can do the same job alone in 12*16 days.

30 men can do the same job in 12*16/30 days.

Tried enough already?
Click here to See SolutionHide Solution
Let assume he had x toys and bought it for Rs.y per piece.
Now, we can form these two equations from these
x*y = 900;//Total cost
(y+2)(x-5) = 900+80;//as he mad profit of Rs.80 by selling x-5 toys in Rs.(y+2).

xy + 2x -5y -10= 900+80;
2x-5y = 90;
2x-5*900/x = 90
2x^2 -4500 = 90x;
x^2 -45x – 2250 = 0;
(x-75)(x+30) = 0;
x = 75 and x =–30, as number of toys cant be negative, initial number of toys were 75.
Initial Cost = 900/75 = Rs.12.
