1). An empty jar weighs wl gm. The jar half filled with a liquid weights w2 gm. find the weight of the jar. Completely filled with the same liquid.

  1. 2w+wl.
  2. 2(w2-w1)
  3. 2w2-wl
  4. 2(w2+wl)

Explanation :

   Full empty jar = w1

Half jar liquid + jar = w2

Then , Full jar of liquid + 2 jar = 2w2

  • Full jar of liquid + jar = 2w2 –w1

2). A strip of paper 100m long, 4cm wide and 0.1mm thick is wound round a cylindrical Core of diameter 10 cm and height 4cm. What is the diameter of the cylinder now?

A. 41.2cm2

B.40cm3

C. 43.5cm

D. 63 cm

Answer : Option A

Explanation :

Volume of core = 22/7*10/4*10/4*4cm3

 Volume of core with paper = 22/7*d/4*d/4*4cm3

 Volume of paper alone = 22/7[d2/16-102/16]*4cm2

                                           = 22/7*[d2-100/4]cm3

  Also, volume of paper = 22/7*100*100*4*0.1/10cm3

                                          = 100*22/7*400*0.1/10cm3

                                          = 400cm3 400*22/7

                                          = 22/7(d2-100)/4 d 2

                                         = sqrt(1700) = 41.2(approx)

B.Rs. 400

C.Rs. 600

D.Rs. 450

Answer :Option B

Explanation :

A’s one day work = 1/6

B’s one day work = 1/8

C’s one day work            = 1/3 – (1/6 +1/8)

                                        = 1/3 – 7/24

                                        = 8- 7/24 = 1/24

C’s three days work        = 3 / 24

                                        = 3/24 * 3200

                                        =  Rs. 400

7.How many seconds will a 500 meter long train take to cross a man walking with a speed of 3 km/hr in the direction of the moving train if the speed of the train is 63 km/hr ?

A.25

B. 30

C.40

D.45

Answer : Option B

Explanation

Relative speed = 60 – 3 = 60 km/hr

                        = 60 * 5/18

                        = 50/3 m/s

Time taken to cross the man = Distance / Speed

                            = 500 / 50/3

                            = 30 seconds

 8. A began a business with Rs. 85,000. He was joined afterwards by B with Rs. 42,500. For how much period does B join ,if the profit at the end of the year are divided in the ratio 3 : 1 ?

Answer : Option D

Explanation :

A shared Rs. 85,000 for 12 months and B shared Rs.42,500 for x months.

 So, (85,000 * 12 ) : (42,500 * x) = 3 : 1

      85,000 * 12 / 42,500x = 3

      85,000 * 12 = 42,500 * 3x

           2 * 12 = 3x

      Hence,    x = 8 months

12. A is two years older than B who is twice the old as C. If the total ages of A,B and C be 27 then how old is B ?

A.7

B.8

C.9

D. 10

Answer : Option D

Explanation

Let the age of C be x years, then the age of B will be 2x years and A will be (2x + 2)years.

Given the sum of their ages = 27

  (2x+2) + 2x + x = 27

           5x + 2 = 27

               5x = 25

                X = 5 years

Thus the age of B = 10 years.

 13.In a mixture of 60 litres, the ratio of the milk and water is 2:1. If the ratio is to be 1:2 the quantity of water to be further added is ?

A.20 litres

B.30 litres

C.40 litres

D.60 litres

Answer: Option D

Explanation:

Quantity of Milk = 60*(2/3) = 40 liters
Quantity of water = 60-40 = 20 liters

As per question we need to add water to get quantity 2:1

=> 40/(20+x) = 1/2 
=> 20 + x = 80
=> x = 60 liters
