Q:

125 over 1000 in Simplest Form?

A) 2/9	B) 1/8
C) 3/8	D) 4/7

Answer & Explanation Answer: B) 1/8

Explanation:

125 over 1000 in Simplest Form means $\frac{125}{1000}$ in its simple fraction form.

Now, to get the simplest form of 125/1000, find the HCF or GCD of both numerator and denominator i.e, 125 and 1000.

HCF of 125, 1000 = 125

Then, divide both numerator and denominator by 125

i.e, $\frac{\frac{125}{125}}{\frac{1000}{125}} = \frac{1}{8}$

Hence, $\frac{1}{8}$ is the simplest form of 125 over 1000.

A) 3	B) 6
C) Both A & B	D) None of the above

Answer & Explanation Answer: C) Both A & B

Explanation:

The given number puzzle can be soved in two ways.

Logic 1 ::

Row 1 - 2 x 3 = 6 , 6 x 3 = 18

Row 2 - 4 x 5 = 20 , 20 x 5 = 100

Row 3 - 3 x 7 = 21 , 21 x 7 = 147

Hence, the missing number could be 3.

Logic 2 ::

Row 1 - 6 x (2+1) = 18

Row 2 - 20 x (4+1) = 100

Row 3 - 21 x (6+1) = 147

Hence, the missing number could be 6.

Therefore, 3 or 6 is the right answer.

Q:

Find the quadratic equations whose roots are the reciprocals of the roots of $2 x^{2} + 5 x + 3$ ?

A) $3 x^{2} + 5 x + 2 = 0$

B) $5 x^{2} + 3 x + 2 = 0$

C) $3 x^{2} - 5 x - 2 = 0$

D) None

A) A	B) B
C) C	D) D

Answer & Explanation Answer: A) A

Explanation:

The quadratic equation whose roots are reciprocal of $2 x^{2} + 5 x + 3 = 0$ can be obtained by replacing x by 1/x.

Hence, 2(1/x)(1/x)+ 5(1/x) + 3 = 0

=> $3 x^{2} + 5 x + 2 = 0$

** IV **
** OT **
** IC **
** NG **
** RA **

Answer

Given that the next word should start with the ending two letters of the previous word. From this,

The first word is

SHIVER

Now, the next word should start with ER and must contain OT in the middle.

EROTIC

Now, the next word should start with IC and must contain IC in the middle.

ICICLE

Now, the next word should start with LE and must contain NG in the middle.

LENGTH

Now, the next word should start with TH and must contain RA in the middle.

THRASH

Hence, the required five words are SHIVER, EROTIC, ICICLE, LENGTH, THRASH.

A) 215	B) 268
C) 254	D) 216

Answer & Explanation Answer: A) 215

Explanation:

Since each ring consists of six different letters, the total number of attempts possible with the three rings is = 6 x 6 x 6 = 216. Of these attempts, one of them is a successful attempt.

Maximum number of unsuccessful attempts = 216 - 1 = 215.

Q:

The reflex angle between the hands of a clock at 10.25 is

A) 197 1/2	B) 167 1/2
C) 157 1/2	D) 187 1/2

Answer & Explanation Answer: A) 197 1/2

Explanation:

Angle traced by hour hand in 125/12 hrs = (360/12 * 125/12) = $312 \frac{1^{0}}{2}$

Angle traced by minute hand in 25 min = (360/60 * 25) = $150^{0}$

$\therefore$ Reflex angle = $360^{0} - {(312 \frac{1}{2} - 150)}^{0} = 360^{0} - 162 \frac{1^{0}}{2} = 197 \frac{1^{0}}{2}$
