Answer & Explanation

 

1.(D)

Let speed of faster horse = x

& speed of slower horse = y

x + y = 50/1

x + y = 50 —- (I)

50/y – 50/x = 5/6 —- (II)

With the help of option

x = 30 kmph

y = 20 kmph

 

2.(C)

Total distance = 17*10=170

Let Journey travelled by auto in x hr

25 * x + (10-x ) 5 = 170

25 x + 50 – 5x = 170

x = 6

Required Ans = 6 * 25 = 150 km

 

3.(B)

S1/S2 = (9/16)^1/2

S1/S2 = ¾

3 = 120

4 = 160

 

4.(C)

Distance covered in 3 minute = 3*(1000/60) = 50

Now he has to cover (500+50) meters in (30-3) minutes

Required speed = (550/1000)/(27/60) = 11/9 km/h

 

5.(B)

Let Speed of train x = a kmph

& Speed of train y = b kmph

a + b = 300/3 = 100 kmph

The faster trains takes be atleast = (3+2) hr = 5 hr

i.e speed of slower train = 40 kmph

i.e time = 300/40 = 7.5 hr

 

6.(B)

Let the time token in first third part of the Journey be x minute, then  the required in second third part of the Journey is 3x/2 & in the last third part of the Journey time required is 15x/8

i.e x+3x/2+15x/8=350 min

x = 80 min

 

7.(A)

From 1st condition

48/u+72/d = 12 —- (I)

72/u+48/d = 13 —- (II)

From eq (I) & (ii)

u = 8 kmph

d = 12 kmph

Speed of streem = (12-8)1/2 = 2 kmph

 

8.(B)

D = 9/2 = 4.5 kmph

U = 9/6 = 1.5 kmph

x = (4.5+1.5) 1/2 = 3.5 kmph

y = (4.5-1.5)1/2 = 1.5 kmph

 

9.(C)

Let speed of 1st train = x m/s

& speed of other train = y m/s

(d/x)/(d/y) = 4/5

y/x = 4/5

Required time = (d+d)/(x+y)

= (4x+5y)/(x+y)

=( 4*5+5*4)/(4+5) = 40/9

 

10.(B)

Let speed of 1st train = x kmph

& speed of 2nd train = (x+10) kmph

So,

X*10 = (x+10) 8

X= 40 kmph

Required Average speed = (2*40*50)/(40+50) = 44(4/9)

Answer & Explanation

 

  1. 2

 

2.1

 

  1. 2;

Second highest number = 746;

746/2 = 373

Third highest number = 519.

Difference = 519 – 373 = 146

 

  1. 4;

519 = 915;

328 = 823;

746 = 647;

495 = 594;

837 = 738;

Lowest number = 594

 

  1. 5;

519 = 951;

328 = 832;

746 = 674;

495 = 549;

837 = 783

Highest number = 951 or 519

  1. 5;From I, ‘a’ is a prime number. But a unique value of a is not known, a can be 2, 3, 5, 7……… Hence, statement I

alone is not sufficient. From II, again a unique value of a

is not known, a can be 2, 4,6…Hence statement II alone is not sufficient. Combining I and II, that ‘a’ is even and

prime. Hence, I and II together are sufficient to answer

the question.

  1. 4; From I and II, we get 2 equation in two variables. But

they are dependent. Thus, eventually we get one equation in two variables, which have infinite solution set.

  1. 3
  2. 2
  3. 1; Check option by pick method.

By options

1) W = X < Y <= A = B >= C >= D
