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

Length of a rectangle is increased by 10%, and breadth is decreased by 10%. Find the percent effect in the area.

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 5 Let length = l

And breadth = b

Area = lb

After increment, length = l x (100 + 10)/100 = l x 110/100 = l x 11/10

After decrement, breadth = b x (100 - 10)/100 = b x 90/100 = b x 9/10

Area = l x 11/10 x b x 9/10

= 99lb/100 lb

% decrease = (lb - 99lb/100)/lb x 100

= (100lb - 99lb)/100 x 1/lb x 100

= lb/100 x 1/lb x 100

= 1%

45x = 180o

X = 4

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

Aman donated 10% of his Savings to Charity and gave 15% of his savings to his sister. Of the remaining savings his gave 60% to his son and gave 80% of the still remaining saving to his daughter. If the sum of the money given to sister and the money left with Aman finally is Rs 84,000, what was his savings?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 7

Let his savings be Rs 100x

Money donated to charity = Rs 10x and Money given to sister = Rs 15x

Money left with Aman = 100x - 10x - 15x = Rs 75x

Money left with him after giving to son = (40/100)*75x = Rs 30x

Money left with him after giving to daughter = (20/100)*30x = Rs 6x

Given, 15x + 6x = 84000

⇒ 21x = 84000

⇒ x = 4000

His Savings = Rs 4,00,000

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

The ratio of 4th and 2nd term of an A.P of positive terms is 5:3 and the product of the 1st and the 3rd terms is 72. what is the product of the 5th and 6th terms of the AP?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 8 Let the first term be 'a' and the common difference be 'd'.

Given, (a + 3d)/(a + d) = 5/3

⇒ 3a + 9d = 5a + 5d

⇒ 2a = 4d

⇒ a = 2d

Also, a(a + 2d) = 72

⇒ 2d(2d + 2d) = 72

⇒ 8d2 = 72

⇒ d2 = 9

⇒ d = 3

∴ a = 2*3 = 6

d ≠ −3 as the 1st term will become a = 2(−3) = − 6 but all terms are positive.

5th term = a + 4d = 6 + 4*3 = 18

6th term = 18 + 3 = 21

Required product = 18*21 = 378

RRB JE EEE (CBT I) Mock Test- 5 - Question 9

Three pipes A, B, and C can fill a cistern in 10 hrs. After working together for 4 hours, C is closed, and A and B fill the cistern in 9 hrs. Then find the time in which the cistern can be filled by pipe C?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 9 A, B, and C can fill in 1 hour = 1/10 of the cistern

A, B, and C can fill in 4 hour= 4/10 =2/5 of the cistern

Remaining part = 1 - 2/5 =3/5 of cistern

3/5 of the cistern is filled by A+B in 9 hours

Therefore, A and B can fill the cistern in 9*5/3 = 15 hrs.

Hence in one hour C filled the cistern = 1/10 - 1/15 = 1/30 of the cistern

Hence C can fill the cistern in 30 hrs.

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

If the average of twelve consecutive even numbers is 113, find the sum of the 3rd and 8th numbers among them?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 10 Let the 1st number = x

According to the question,

x + (x+2) + (x+4) + ...... + (x+22) = 113*12

12x + 132 = 1356

12x = 1224

x = 102

Therefore 3rd number = 102 + 4 = 106

8th number = 102 + 14 = 116

Hence the required answer = 106 + 116 = 222

RRB JE EEE (CBT I) Mock Test- 5 - Question 27

Downstream speed of boat A is 20% more than the downstream speed of boat B whose upstream speed is 6 km/hr less than upstream speed of boat A. What is the speed of boat A in still water? The stream for both boat is moving with 10 km/hr.

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 27 Stream speed = 10 km/hr

Downstream speed of boat A = (6/5) x downstream speed of boat B

Upstream speed of boat A - upstream speed of boat B = downstream speed of boat A - downstream speed of boat B = 6

(6/5) x downstream speed of boat B - downstream speed of boat B = 6

Downstream speed of boat B = 30 km/hr

Downstream speed of boat A = 30 + 6 = 36 km/hr

Speed of boat A in still water = 36 - 10 = 26 km/hr

RRB JE EEE (CBT I) Mock Test- 5 - Question 28

If monthly income of a person is increased by 20% and his expenditures are increased by 40%, then his savings are decreased by what percent? (ratio of income and expenditure is 4: 3 respectively.)

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 28 Let income and expenditure are 'a' and 'b' respectively.

Savings = a - b = a - 3a/4 = a/4

When income and expenditure are increased by 20%. Then,

New income = 120% of a = 1.2a

New expenditure = 140% of b = 1.4 x 3a/4 = 2.1a/2

New savings = 1.2a - 2.1a/2 = 3a/20

Decrement in savings = (a/4) - (3a/20) = a/10

Percentage = a/10)/(a/4 x 100 = 40%

RRB JE EEE (CBT I) Mock Test- 5 - Question 29

A and B can finish a work in 2 days, B and C in 3 days and A and C in 4 days. Find the ratio of time taken by A alone and C alone to finish the work?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 29 Suppose A, B and C take A, B and C days respectively to finish the work on their own.

1/A + 1/B = 1/2 (1)

1/B + 1/C = 1/3 (2)

1/A + 1/C = 1/4 (3)

(1)+(2)+(3) ⇒ 2(1/A+1/B+1/C) = 13/12

⇒ 1/A + 1/B + 1/C = 13/24 (4)

(4) - (2) ⇒ 1/A = 5/24

Thus A takes 24/5 = 4.8 days.

(4) - (1) ⇒ 1/C = 1/24

Hence C takes 24 days.

Required ratio = 4.8: 24 = 1:5

Where does the oxygen that keeps us alive come form?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 73 Since water and carbon dioxide are both compounds which contain oxygen, it is possible to obtain oxygen from either. The oxygen produced from photosynthesis is not released into the air. It is not until cellular respiration that oxygen is released. the oxygen comes from water. The water molecules are split at the “beginning” of photosynthesis for the electrons. These electrons eventually make their way to the electron transport chain, where oxygen is the final electon accept, and then released into the air. Scientists agree that there’s oxygen from ocean plants in very breath we take. Most of this oxygen comes from tiny ocean plants – called phytoplankton-that live near the water’s surface and drift with the currents. Like all plants, they photosynthesize-that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen.

A boat will submerge when it displaces water equal to its own _______

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 5 - Question 80 A boat will float when the weight of the water it displaces equals the weight of the boat and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge. Floating of the boat works on the principle of buoyancy force which is an upward force exerted by a liquid, gas or other fluid, that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus a column of fluid, or an object submerged in the fluid, experiences greater pressure at the bottom of the column than at the top. This difference in pressure results in a net force that tends to accelerate an object upwards.
