4)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A) 90 m

wrong answer

B) 102 m

wrong answer

C) 108 m

wrong answer

D) 96m

right answer

solution: 96

explanation:

let x be the distance between the point they first met
Total time taken by the two willbe equal
so (x+30)*8/11 = (198-x)
x= 102m

distance travelled by krishna= 198-102 = 96m

5)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A) 200 miles 

right answer

B) 180 miles 

wrong answer

C) 320 miles 

wrong answer

D) 150 miles 

wrong answer

solution: 200

explanation:

if speed of ship=s then seaplane speed=10s
let distance of ship be x
then seaplane distance =180+x
because ships traveled 180 miles after that plane started it journey,so plan has to cover those 180 miles.
Therefore
x / s = (180 + x )/10s
x = 20
Hence total distance = 180+20=200 miles

6)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A) d = 1 & g = 9

wrong answer

B) d = 1 & g = 5

wrong answer

C) d = 5 & g = 1

right answer

D) d = 2 & g = 6

wrong answer

solution:  d = 5 & g = 1

explanation:

Step 1:
a + b + c + d = d + e + f + g = g + h + i = 17

Means,
(a + b + c + d) + (d + e + f + g) + (g + h + i) = 17 +17+17
(a + b + c + d) + (d + e + f + g) + (g + h + i) = 51
i.e.
a + b + c + d + e + f + g + h + i + ( d + g ) = 51....(I)

Step 2: 
But Each letter taken only one of the digit from 1 to 9.
So, a + b + c + d + e + f + g + h + i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45

a + b + c + d + e + f + g + h + i =45....(II)
Step 3: 
From (I) and (II) we get,
( a + b + c + d + e + f + g + h + i + ( d + g ) ) - ( a + b + c + d + e + f + g + h + i )=51-45
d + g = 51 - 45 = 6

possible values of d & g are (1, 5), ( 5,1 ), (2,4) & (4, 2 )
( 2, 4 ) & ( 4 , 2 ) are not possible as "a = 4 "
We have to try with other values (1, 5 ) & ( 5 , 1 )

Step 4:

Case 1:
When d = 1 and g = 5
1. a + b + c + d = 4 + b +c + 1 = 17
b + c = 12
only possible values of b & c are ( 9, 3 ) or ( 3, 9 )

2.d + e + f + g = 1 + e + f + 5 = 17
e + f = 11

possible combinations for 11 are (2,9) ; (3,8) ; (4,7) & (5,6).
Out of the above four combinations nothing is possible because b & c takes values 3 & 9, g = 5 (assumed) and a = 4 (given).
So, d = 1 & g = 5 is not the solution.

Case 2: 
When d = 5 and g = 1
1. a + b + c + d = 4 + b + c + 5 = 17
b + c = 17 - 9 = 8
only possible combination is 2 & 6
a + b + c + d = 4 + ( 2 + 6 ) + 5 = 17
2. d + e + f + g = 5 + e + f + 1 = 17
e + f = 17 - 6 = 11
The only possible value is 3 & 8
d + e + f + g = 5 + ( 3 + 8 ) + 1 = 17
g + h + i = 1 + h + i = 17
h + i = 17 - 1 = 16
The only possible value for h & i are 7 & 9
g + ( h+ i ) = 1 + ( 7 + 9 ) = 17

So the values of d = 5 & g = 1

7)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A) 16

wrong answer

B) 64

wrong answer

C) 24

wrong answer

D) 32

right answer

solution:  32

explanation:

First we have to arrange A,
there is 1 way for it.
for second person B,
there are 2 option one left and one right.
for third person C, 2 option are there same as for B similarly for others,
so total number of possibility = 1*2*2*2*2*2 = 32 

so all possible combination is:

A,B,C,D,E,F ; B,A,C,D,E,F ; C,A,B,D,E,F ; D,A,B,C,E,F ; E,A,B,C,D,F ; F,A,B,C,D,E

F,E,A,B,C,D ; E,D,A,B,C,F ; F,D,A,B,C,E ; D,C,A,B,E,F ; E,C,A,B,D,F ; F,C,A,B,D,E

C,B,A,D,E,F ; D,B,A,C,E,F ; F,B,A,C,D,E ; E,B,A,C,D,F ; F,E,D,A,B,C ; F,E,C,A,B,D 

E,D,C,A,B,F ; F,D,C,A,B,E ; E,D,B,A,C,F ; F,D,B,A,C,E ; D,C,B,A,E,F ; E,C,B,A,D,F

F,C,B,A,D,E ; F,E,D,C,A,B ; F,E,D,B,A,C ; F,E,B,A,C,D ; F,E,C,B,A,D ; E,D,C,B,A,F

9)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A) 18

wrong answer

B) 20

right answer

C) 15

wrong answer

D)21

wrong answer

solution:  20

explanation:

Let a be the initial quantity (in relevant units) of grass and b be the amount of grass grown per day.
Then, 60 x 30 = 1800 = a + 60b and 24*70= a + 24b.
Solving these equations, we get
36b = 120
b = 10/3, a = 1600
cows are needed to eat the grass in 96 days
x*96 = a+96b
x*96 = 1600+96(10/3)
x = 1920/96 = 20.

10)Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h.

Time:  

A)262144

right answer

B)4^8

wrong answer

C)262244

wrong answer

D)263144

wrong answer

solution:  x = 4^9=262144

explanation:

X^(1/3) - X^(1/9) =60.
let x^(1/9) =y
y^3-y =60
y^3-y-60=0
y=4
x^(1/9)= 4
x = 4^9=262144
