Q:

Express 0.875 and 0.375 as a Fraction.

A) 3/11 & 7/11	B) 7/9 & 9/13
C) 7/8 & 3/8	D) 7/9 & 9/11

Answer & Explanation Answer: C) 7/8 & 3/8

Explanation:

Given 0.875 and 0.375

0.875 ::

After decimal point there are 3 digits 875

Now, mutiply and divide 0.875 with 1000

$0.875 x \frac{1000}{1000} = \frac{875}{1000} Now, this can be reduced to fraction \frac{7}{8} Therefore, 0.875 as fraction = \frac{7}{8}$

Similarly,

0.375 ::

After decimal point there are 3 digits 375

Now, mutiply and divide 0.375 with 1000

$0.375 x \frac{1000}{1000} = \frac{375}{1000} Now, this can be reduced to fraction \frac{3}{8} Therefore, 0.375 as fraction = \frac{3}{8}$

Q:

Eight first class and six second class petty officers are on the board of the 56 club. In how many ways can the members elect, from the board, a president, a vice-president, a secretary, and a treasurer if the president and secretary must be first class petty officers and the vice-president and treasurer must be second class petty officers?

A) 1500	B) 1860
C) 1680	D) 1640

Answer & Explanation Answer: C) 1680

Explanation:

Since two of the eight first class petty officers are to fill two different offices, we write $8 P_{2} =$ 56

Then, two of the six second class petty officers are to fill two different offices; thus, we write $6 P_{2}$ =30

The principle of choice holds in this case; therefore, the members have 56 x 30 = 1680 ways to select the required office holders

Q:

Tanks A and B are each in the shape of a right circular cylinder. The interior of tank A has a height of 10 meters and a circumference of 8 meters, and the interior of tank B has a height of 8 meters and a circumference of 10 meters. The capacity of tank A is what percent of the capacity of tank B ?

A) 76%	B) 72%
C) 80%	D) 82%

Answer & Explanation Answer: C) 80%

Explanation:

circumference of A = $2 πr$ = 8 => so r = $\frac{4}{π}$
volume = $π \times {(\frac{4}{π})}^{2} \times 10$ = $\frac{160}{π}$
circumference of B = $2 πr$ = 10 => so r = $\frac{5}{π}$
volume = $π \times {(\frac{5}{π})}^{2} \times 8$ = $\frac{200}{π}$
so ratio of capacities = 160/200 = 0.8
so capacity of A will be 80% of the capacity of B.

Q:

The area of a square is equal to the area of a rectangle. The length of the rectangle is 5 cm more than a side of the square and its breadth is 3 cm less than the side of the square. What is the perimeter of the rectangle ?

A) 15 cm	B) 18 cm
C) 34 cm	D) 26 cm

Answer & Explanation Answer: C) 34 cm

Explanation:

Let the side of the square be 's' cm

length of rectangle = (s+5) cm

breadth of rectangle = (s-3)cm

(s+5) (s-3) =

$s^{2}$ - 5s - 3s - 15 = $s^{2}$

2s = 15

Perimeter of rectangle = 2(L+B) = 2(s+5 + s–3) = 2(2s + 2)

= 2(15 + 2) = 34 cm

Q:

The B.G. on a certain sum 4 years hence at 5% is Rs. 200. What is the present worth?

A) Rs. 4500	B) Rs. 6000
C) Rs. 5000	D) Rs. 4000

Answer & Explanation Answer: C) Rs. 5000

Explanation:

T = 4 years

R = 5%

Banker's Gain, BG = Rs.200

$T D = \frac{B G \times 100}{T R} = \frac{200 \times 100}{4 \times 5} = R s . 1000$

$T D = \sqrt{P W \times B G}$

$\Rightarrow 1000 = \sqrt{P W \times 200}$

=>PW = Rs.5000
