A. 10 hours

B. 15 hours

C. 12 hours

D. 13 hours

Explanation:

A can copy 50 papers in 10 hrs., while A & B can copy 70 papers in 10 hrs.

It means B can copy 20 papers in 10 hrs.

Then time taken by B to copy 26 papers = 26*10/20 = 13 hours.

A. 44kmph

B. 30 kmph

C. 36 kmph

D. 40 kmph

Explanation:

Total distance travelled = 24*(20+5) = 600 kms

distance travelled by bus = 20*20=400 kms

distance travelled by train = 600-400=200kms

Average speed of train = 200/5=40 kmph.

3. The length and breadth of a square are increased by 40% and 30% respectively. The area of the resulting rectangle exceeds the area of the square by:

A. 42%

B. 62%

C. 82%

D. None

Explanation:

Area of square = x2.

Increment of length = 1.4x.

Increment of breadth = 1.3x

Area of rectangle = l×b = 1.82 x2.

Increment in area= 1.82 x2 - x2 = 82%.

4. The average salary per month of 30 employees in a company is Rs. 4000. If the manager's salary is added, the average salary increases to Rs. 4300, what is the salary of the manager?

A. Rs. 10000

B. Rs. 13000

C. Rs. 12000

D. Rs. 13300

Explanation:

Let total salary of the emp=30*4000=1,20,000

Now,

By adding one member that is Manager =31

So,

Total salary of the emp=31*4300=1,33,300

Net salary of the manager =1,33,300-1,20,000=13300.

5. The ratio of the ages of A and B is 9:5. After 8 years B would reach the present age of A. Find the present ages of B and A respectively.

A. 9, 5

B. 10, 18

C. 18, 10

D. 5, 9

E. 5, 7

Explanation:

Let the present age of A & B be 9x and 5x.

According to the condition,

=> 5x + 8 = 9x

=> 4x = 8.

=> x = 2.

Therefore, the present age of A = 9 * 2 = 18 and B = 5 * 2 = 10.

6. Find [(4/7) ^3-(3/7) ^3]/ [(4/7) ^2-(3/7) ^2] =?

A. 31/49

B. 39/49

C. 37/49

D. 34/49

Explanation:

From the question,

(4/7) ^3-(3/7) ^3= [(4^3) -(3^3)]/ (7^3)

= (64-27)/ (7^3)

=37/343.

And,

(4/7) ^2-(3/7) ^2= [(4^2) -(3^2)]/ (7^2)

= [16-9]/ (7^2) =7/49.

Therefore, the required answer:

=> (37/343)/ (7/49) = (37*49/343)/7

=> (37/7)/7 = 37/49.

7. The average weight of 8 men is increased by 1.5 kg when one of the men who weighs 65 kg is replaced by a new man. The weight of the new man is:

A. 76 kg

B. 76.5 kg

C. 76.7 kg

D. 77 kg

Explanation:

Let x be the average weight of 8 men (before replacement). Therefore (x+1.5) will be the average weight of 8 men (after replacement)

=> (7*x + 68)/8 = x.

=> x = 65.

=> (7*x + new)/8 = x + 1.5.

New = (8*65+8*1.5 – 8*65) = 65+12 = 77.

8. If radius of a circle is diminished by 10% then its area is diminished by

A. 10%

B. 19%

C. 20%

D. 36%

Explanation:

Let, the old radius be 'r'.

New r=100-10)/100= 0.9r.

Old area=3.14 *r2

New area=3.14 * 0.81r2

Hence, % decrease= [3.14 r2(1-0.81)] *100/3.14 r2 = 19%.

9. Coding-Decoding:
