RRB JE CE (CBT I) Mock Test- 5 - Question 4

A horse takes 2(½) seconds to complete a round around a circular field. If the speed of the horse was 66 m/s, then the radius of the field is :[Given π=22/7]

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 4
Distance covered in one round

= Circumference of circle

= 2πr

Speed = 66 m/s

Time = 5/2

S=D/T

D=S×T

=66×(5/2)

D=165m

2π=165

=2×(22/7)×t=165

R = (165x7)/44 = 26.25m

RRB JE CE (CBT I) Mock Test- 5 - Question 5

In a mixture of 60 litres, the ratio of milk and water is 2 : 1. What amount of water must be added to make the ratio of milk and water as 1 : 2?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 5
Milk in the original mixture is (2/3)×60= 40 litres and water= 20 litres.

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 6
Distance covered by Heena = 2 x 5 = 10 Km

Distance Covered by Meena = 4 x 5 = 20 Km

Total distance = (10 + 20) = 30Km

RRB JE CE (CBT I) Mock Test- 5 - Question 7

A man can row 15 kmph in still water and he finds that it takes him twice as much time to row up than as to row down the same distance in the river. The speed of the current is :

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 7
Let the speed of current be x kmph

∴ Down stream speed = 15 + x kmph

Up stream speed = 15 - x kmph

Let the distance be d km.

∴ Down stream time = d/(15+x)

Upstream time = d/(15-x)

According to question,

2d/(15+x) = d/(15-x)

⇒ 2(15 - x) = (15 + x)

⇒ 30 - 2x = 15 + x

⇒ 15 = 3x

⇒ x = 15/3 = 5

∴ speed of current = 5 kmph

RRB JE CE (CBT I) Mock Test- 5 - Question 8

For what value of m, the system of equations mx + 2y =2 and 3x + y = 1 will be coincident?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 8
Two linear equations will coincide if there are infinite number of solutions,

I.e. a1/a2 = b1/b2 = c1/c2

for a1 x +b1 y = c1

and a2x +b2y = c2

∴ m/3 = 2/1 = 2/1

⇒ m = 6

RRB JE CE (CBT I) Mock Test- 5 - Question 10

if x+y = 25 and x2y3 +y2x3 =25, what is the value of xy?

Detailed Solution for RRB JE CE (CBT I) Mock Test- 5 - Question 10

x2y3 +y2x3 =25

⇒ x2 y2 (x + y) = 25

⇒ (xy)2 (x + y) = 25

⇒ (xy)2 = 1

(∵ x + y = 25)

⇒ xy = ± 1
