TCS NQT Symbol and Notations Quiz-1

'+' means '*', '*' means '-', '-' means '/' and '/' means '+'.
The given expression is
9 + 4 - 6 * 6 / 8
On converting this expression as per the directions, we get the expression
9 * 4 / 6 - 6 + 8
We simplify this expression using BODMAS rule,
9 * 4 / 6 - 6 + 8 = 36 / 6 - 6 + 8 = 8.

4^3+5^3=64+125 =189

is 4⊚5

10^3+8^3
=1000+512 =1512 =10⊚8

Similarly 6⊚9
=63+93 =216+729 =945.

The given expression
16 * 4 / 4 + 14 - 2
becomes
16 - 4 + 4 * 14 / 2
as per the given directions.
Using BODMAS rule,
16 - 4 + 4 * 14 / 2
= 12 + 56 / 2
= 12 + 28
= 40

The given expression
(13 - 5 * 8 + 4) * (5 - 6 + 12 * 3) / (4 + 2)
becomes
(13 + 5 - 8 / 4) - (5 + 6 / 12 - 3) * (4 / 2)
Using BODMAS rule,
(13 + 5 - 8 / 4) - (5 + 6 / 12 - 3) * (4 / 2)
= (18 - 2) - [5 + (1/2) - 3] * 2
= 16 - (5/2) * 2
= 11

Explanation:

Using the correct symbols , we have: Given expression = 4*11-5+55=94

By replacing question mark with '≥' symbol. We get,
K > M ≥ N ≥ O ≥ P ≥ Q.

B,C and H are the three letters which are followed by a digit but not immediately preceded by a consonant.

From choice(1), P ≤ Q, we cannot say definitely P < Q.
From choice (2), we cannot determine relation ship between P and Q.
From choice (3), we cannot determine relation ship between P and Q.
From choice (4), P R definitely follows.

In choice (3), R > P, hence R ≤ P definitely follows.

The fifteenth element from the right is ↓.
The element which is tenth to the right of this element is D.
