RRB JE EEE (CBT I) Mock Test- 3 - Question 1

### If sinθ + sin2θ = 1, then the value of cos12θ + 3 cos10θ + 3 cos8θ + cos6θ – 1 is:

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 1

sinθ + sin2θ = 1 ⇒ sinθ = cos2θ

Given : cos12θ + 3 cos10θ + 3 cos8θ + cos6θ–1

= (cos4θ + cos2θ)3 – 1 = (sin2θ + cos2θ)3 – 1 = 1 – 1 = 0

Thus, side of equilateral triangle = 8 cm. Area of equilateral triangle RRB JE EEE (CBT I) Mock Test- 3 - Question 3

### If 10 men can do ork in 6 days and 15 women can do the same in 5 days, Then 8 men and 5 women can together do the work in :

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 3 10 Men can do the work in 6 days

If the work is to be finished in 5 days, number of women required = 15

If the work is to be finished in 6 days, number of women required =[15×5]/6 = 25/2

So that 10 men = 25/2 women

or 5 women = 4 men

8 men + 5 women = 8 men + 4 men = 12 men

Now 10 men can finish the work in = 6 days

∴ 12 men can finish the work in [6×10]/12=5 days

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 9 RRB JE EEE (CBT I) Mock Test- 3 - Question 10

A man sells two scooters for Rs.12000 each. He makes a profit of 20% on one and a loss of 20% on the other. The profit/loss, on the whole, is

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 10

SP1 = 12000

profit = 20%

∴ CP1 = 12000/120 x 100 = Rs.10,000

SP2 = 12000

Loss % = 20%

∴ CP = 12000/80 x 100 = Rs.15,000

Total CP = 25000

Total SP = 24000

Loss = Rs.25000 – Rs.24000 = Rs.1000

(or)

If the selling price of the two items is equal and the percentage of profit on one equals the percentage of loss on the other, then, the result is always loss and the percentage of loss is (loss%2/100).

Hence, in the present case, loss percentage = (20)2/100 percent = 4%.

Loss = 4/96 × Rs.24000 = Rs.1000

RRB JE EEE (CBT I) Mock Test- 3 - Question 11

The pie chart given here shows expenditures incurred by a family on various items and their savings, which amount to Rs. 8,000 in a month.

Study the chart and answer the questions based on the pie chart. The ratio of the expenditure on food to the savings is:

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 13

Expenditure on food

=(120/300)×40,000= Rs. 16,000

Required ratio = 16000 : 8000 ⇒ 2 : 1

RRB JE EEE (CBT I) Mock Test- 3 - Question 14

A solid metallic cone of height 10 cm and radius of base 20 cm is melted to make spherical balls each of 4 cm diameter. How many such balls can be made?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 14

Volume of cone = 1/3πr2h

=(1/3)×π×(20)2×10

=400×10

=(π/3)×4000=(4000/3)π

Volume of spherical balls = 4/3πr3

=(4/3)×π×(2)2

= 32/3π

∴ Spherical balls are formed from the cones.

∴ Total volume of all spherical cones = Volume of cones.

∴ No. of spherical balls = Volume of cone/Vol of 1 spherical ball

=4000/3

=32/3

=4000/32=125

The simple interest on a certain principal at the rate of 9.5 percent per annum is Rs 950 for two years. How much will be the additional interest on the same amount for the same period at the rate of 10.5 percent per annum?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 20

S.I. = Rs 950, rate = 9.5%

time = 2 years

∴ sum =(950×100)/(9.5×2)=5000

If the rate of interest is 10.5% then.

Simple Interest=(5000×2×10.5)/100=Rs 1050

∴ additional interest due to change in the a rate of interest =Rs 100

RRB JE EEE (CBT I) Mock Test- 3 - Question 21

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 24

Effective decrease

= [20 – 20 – 20×(20/100)] % = -4%

∴ Present cost of the article = 96% of Rs.75

= (75×96)/100 = Rs.72

What will be the area of a rhombus, whose one side is 20 cm and one diagonal is 24 cm?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 27 Let length of another =diagnol =2x

Diagnols of a rhombus intersect at right angles, so buy using pythagorus theorem,

X2 + 122 = 202

Therefore x =16, so diagonal = 2 x 16 = 32

Area of rhombus  RRB JE EEE (CBT I) Mock Test- 3 - Question 28

The ratio of two unequal sides of a rectangle is 1 : 2. If its perimeter is 24 cm, then the length of diagonal in cm is:

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 28

Let the sides of rectangle be 2x, x cm

∴ Perimeter of rectangle = 2 (2x+x)

2 (2x+x) = 24

or 6x = 24

∴ x = 4 cm

hence length of diagonal = √[(2x)2+x2]

= √5x2

= √(5×16)

=√ 80

= 4√5

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 29

1 man done work in 6×6×9 hours

Since 8W=6M=12B

therefore 12M+12W+12B=27M

therefore 27 men will do work in (6×6×9/27)=12 hours

=12/8=1.5 days

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 3 - Question 49 Z is older than only two persons.

We get,

___ < ___ < Z

Then,

T is younger to both W and V.

We get,

T < W, V

Since,

Y is younger to neither Z nor T, who is older than both S and Z.

We get,

___ < ___ < Z < T < W, V, Y

Only S and U are left and, we know,

U is younger to at least three persons, none of whom is S.

So, we get,

S < U < Z < T < W, V, Y

Hence, T is the one who is younger to as well as elder to same number of persons i.e. 3 persons.
