Solution

7 is Single Digit number remaining other three numbers are double digit numbers.
Hence, option 'A' is correct.
Question 5
1 / -0

A
ACEGF

B
FHJLK

In each option, the first three letters are alternate in normal alphabetic series.
Whereas the last two letters(fourth and fifth) are consecutive in reverse alphabetic series.
But in option D, the last two letters are not consecutive in either order.
Hence, option D is the different one.
Question 6
1 / -0

Find the odd one out from the alternatives.

A
$$2518$$

B
$$2709$$

C
$$3249$$

D
$$8314$$

Solution

In all numbers except $$8314$$, the sum of first three digits is equal to the unit digit.
(A) $$2518\rightarrow 2+5+1=8$$
(B) $$2709\rightarrow 2+7+0=9$$
(C) $$3249\rightarrow 3+2+4=9$$
(D) $$8314\rightarrow 8+3+1 \neq 4$$
Hence, option $$D$$ is the correct answer.

D
$$8210$$

Solution

Except option D, all other are odd numbers.
Question 9
1 / -0

In a certain code, 'COURSE' is written as 'FRXUVH', then how would RACE be written in that code?

A
HFDV

B
UCFH

C
UDFH

D
UDHF

Solution

'COURSE' is written as 'FRXUVH'.
Each letter of the given word moves 3 steps ahead in alphabetic order and get the letter of code. i.e.
C$$+3\rightarrow$$ F,
O$$+3\rightarrow$$ R,
U$$+3\rightarrow$$ X,
R$$+3\rightarrow$$ U,
S$$+3\rightarrow$$ V,
E$$+3\rightarrow$$ H.
Similarly, code for RACE is 'UDFH'.
Hence, option C is correct.
Question 10
1 / -0

In a certain code "GOODNESS' is coded as HNPCODTR, how is GREATNESS' written in that code?

A
HQFZUODTR

B
HQFZUMFRT

C
HQFZSMFRT
