Ashu's mother was three times as old as Ashu 5 yrs ago. After 5 yrs, she will be twice as old as Ashu. How old is Ashu today?

Detailed Solution for RRB Group D Mock Test - 19 - Question 1

The sheet of paper shown in the figure (X) in each problem, is folded to form a box. Choose from amongst the alternatives (I), (II), (III) and (IV), the boxes that are similar to the box that will be formed.
Detailed Solution for RRB Group D Mock Test - 19 - Question 22
The fig (X). is similar to the Form V.
So, when the sheet shown in fig, (X) is folded to form a cube then the shaded face lies opposite to one of the blank faces, the face bearing a circle lies opposite to another blank face and the face bearing a shaded square lies opposite to the third blank face.
Thus, each one of the cubes shown in figures (I), (II) and (IV) can be formed.
Also, though the cube shown in fig. (III) has faces that can appear adjacent to each other but the cube formed by folding the sheet in fig. (X) cannot be rotated to form fig. (III) .
Hence, the cube in fig. (III) cannot be formed.
