The numbers greater than 1 are to be written only by using the two symbols given above. The value of the symbol for 1 double itself every time it shifts one place of the left. study the following examples.

'0' is written as α

'1' is written as ß

'2' is written as ßα

'3' is written as ßß

'4' is written as ßαα

And so on.

Which of the following will represent the LCM of 10, 15 and 18?

Direction (Q. 6 - 10): In each of the questions given below which one of the five answer figures on the right shouk come after the problem figures on the left, if the sequence were continued ?

In each subsequent figure, one design of each column is replaced with a new design. And when all the three designs are replaced with new designs, the previous designs begin to appear stepwise.

In each subsequent figure, the designs move half a step and one step alternately in anticlockwise direction and two adjacent designs interchange positions. In each subsequent figure, one new design is introduced in front of the pre-existing designs.

In each subsequent figure, the plane of designs rotates through 45° and 90° anticlockwise alternately. In the first step, one of the three designs moves to the middle and the other two designs interchange positions with the designs of the other side. In the second step, one of the two designs moves to the middle position.
