question no 34 (Question:196975.1)

Rule 3 states that if odd number is followed by even number then substract here 18 is followed by 33, then how the rulr applies to it

Question:

DIRECTIONS: In each of the following questions, two rows of numbers are given. The resultant value of the numbers of each row worked out separately based on the following rules.


Rules:

(i) If an odd number is followed by the another odd number, the first number is divided by the second number.

(ii) If an even number is followed by the another even number, which is a perfect square, then both the numbers are to be added.

(iii) If the odd number is followed by the even number, even number is subtracted from the odd number.

(iv) If the even number is followed by the odd number, both the numbers are multiplied.


Note: The operations are applied on number from left to right.

If Z Is the resultant value of the first row, then what Is the resultant value of the second row?


99   3   18

Z    6    3

Options:
A) 3
B) 5
C) 12
D) 18
E) 10
Solution:

Ans : (a) For row 1,

First apply the operation on 99 and 3.

According to rule (I),

99 ÷ 3 = 33

Now, apply the operation on 33 and 18.

According to rule (iii),

33 — 18 = 15

So, the resultant value of row 1 is 15, that is Z.

For row 2,

First assign the value of Z in row 2, the row becomes,

15  6  3

Apply the operation on 15 and 6.

According to rule (iii),

15 — 6 = 9

Now, apply the operation on 9 and 3.

According to rule (i),

9 ÷ 3 = 3

So, the resultant value of row 2 is 3.

Dear student
First apply the operation on 99(odd) and 3(odd).
According to rule (i),odd ÷ second odd
99 ÷ 3 = 33
Now, apply the operation on 33(odd) and 18(even).
According to rule (iii),odd - even
33 — 18 = 15
So, the resultant value of row 1 is 15, that is Z.
For row 2,
Apply the operation on 15(odd) and 6(even).
According to rule (iii),odd - even
15 — 6 = 9
Now, apply the operation on 9(odd) and 3(odd).
According to rule (i),odd ÷ second odd
9 ÷ 3 = 3
So, the resultant value of row II is 3.
