RRB JE ECE (CBT I) Mock Test- 10 - Question 14

A man rowed a boat to a place covering 72 km distance and back in 15 hours. He finds that he can row 3 km with the stream in the same time as 2 km against the stream. Find the speed of the stream.

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 10 - Question 14 Speed downstream : speed upstream = 3 : 2

∴ Time taken to row downstream : Time taken to row upstream = 2 : 3

But, total time taken = 15 hours

∴ Time taken to row downstream = 2/5 x 15 hours = 6 hours

And time taken to row upstream = 15 - 6 = 9 hours.

∴ Speed downstream = 72/6 = 12 km/h

And speed upstream = 72/9 = 8 km/h

∴ Speed of the stream = (12-8)/2 km/h

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 10 - Question 15

A : B = 9 : 10

B : C = 5 : 4

C : D = 4 : 5

A : B : C : D = 9 : 10 : 8 : 10

9 = 270

10 = 300

% = 300/500 x 100= 60%

∠AOC + ∠BOC 180°

⇒ 5y + 10 + 2x = 180°

⇒ 5y + 10 + (2 x 20) = 180°

⇒ 5y = 180° - 10 - 40 = 130°

⇒ y = 26°

RRB JE ECE (CBT I) Mock Test- 10 - Question 23

Find the value of (x3+y3+z3 - 3xyz), if x + y + z = 9 and xy + yz + zx = 26:

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 10 - Question 23 Given (x+y+z) = 9

∴ (x + y + z)2 = 92 = 81

∴ x2 + y2 + z2 + 2 × 26 = 81

∴ x2 + y2 + z2 = 81 - 52 = 29

Now, x3 + y3 + z3 - 3xyz

= (x + y + z) [(x2 + y2 + z2)] - (xy + yz + xz)]

= 9 × (29 - 26) = 27

A carriage driving in a fog passed a man who was walking at the rate of 3 km an hour in the same direction. He could see the carriage for 4 minutes and it was visible to him upto a distance of 100 m. What was the speed of the carriage?

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 10 - Question 26 The distance travelled by the man in 4 min = [(3×1000)/60] ×4=200 meters

∴ distance travelled by the carriage in 4 min = (200 + 100) = 300 meters

∴ speed of the carriage = (300/4)×(60/1000) km/hour

= 9/2 km/hour

or 27x° = 6 x 90°

or x = 20°

RRB JE ECE (CBT I) Mock Test- 10 - Question 30

A man's age is 125% of what it was 10 years ago, but 83 1/3 % of what it will be after ten 10 years. What is his present age?

Detailed Solution for RRB JE ECE (CBT I) Mock Test- 10 - Question 30 At present

man age = x years

10 years ago :

Man age = ( x - 10 ) years

10 years after :

Man age = ( x + 10 ) years

According to the problem given ,

125% of (x - 10) = 83⅓% of (x + 10)

(125/100) (x - 10) = (250/300)(x+10)

(5/4) x - 10) = (5/6)(x + 10)

(x - 10)/4 = (x + 10)/6

6(x - 10) = 4(x + 10)

6x - 60 = 4x + 40

6x - 4x = 40 + 60

2x = 100

x = 100/2

x = 50

Therefore ,

Present age of the man = x = 50yrs
