$3$ bricks are taken away from pillar B. $2$ of them are kept on D, and one on C.
What will be the new order of their length?

• A. B, A, C, E, D
• B. B, D, E, A, C
• C. E, A, B, D, C
• D. A, B, E, C, D

Answer 1

The correct option is A B, A, C, E, D

B, A, C, E, D
Say:
On the screen, we have five piles of bricks, arranged in increasing order of their length.

Steps:
Let us first find out how many bricks are there in each pile.
Pile $A:3$
Pile $B:5$
Pile $C:6$
Pile $D:7$
Pile $E:8$

If $3$ bricks are taken away from pillar B, $2$ of them are kept on D and one on C, then let us see how many bricks are there in each pile now.
Pile $A:3$
Pile $B:5-3=2$
Pile $C:6+1=7$
Pile $D:7+2=9$
Pile $E:8$
As per the new numbers, the new order will be:
B, A, C, E,D
Thus, option D is the correct answer.
