Concentrations of three solutions A, B and C are 20%, 30% and 40% respectively. They are mixed in the ratio 3: 5: x resulting in a solution of 30% concentration. Find x

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 1 - Question 3 3 × 0.2 + 5 × 0.3 + x × 0.4 = 0.3 (3+5+x)

⇒ 2.1 + 0.4x = 0.3(8+x)

⇒ 2.1 + 0.4x = 2.4 + 0.3x

or, x = 3

RRB JE EEE (CBT I) Mock Test- 1 - Question 4

If (N)P < (N)q when N > 0 and positive integral

=p < q

If ( N )p < ( N)q when N > 0 and fractional

= p > q

Using these results we get option C is the correct answer.

RRB JE EEE (CBT I) Mock Test- 1 - Question 13

Mahesh grows potatoes in his backyard which is in the shape of a square. Each potato takes 1 cm2 in his backyard. This year, he has been able to grow 137 more potatoes than last year. The shape of the backyard remained a square. How many potatoes did Mahesh produce this year?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 1 - Question 13 Let the area of backyard be x2 this year and previous year was y2

x2−y2 = 137

(x+y) (x-y) = 137 x 1

x + y = 137 ---- (i)

x - y = 1 ---- (ii)

On solving eq. (i) & (ii), we get

x = 69, y = 68

No of potatoes produced this year = 692 = 4761

RRB JE EEE (CBT I) Mock Test- 1 - Question 14

The dimensions of a luggage box are 80 cm, 60 cm and 40 cm. How many sq. cm of cloth is required to cover the box?

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 1 - Question 14 Surface area of a cuboid= 2(lb+bh+lh),

where l= length,

b= breadth,

h= height of the cuboid

Let the length, breadth and height of the luggage be l , b, h respectively

Here, l= 80 cm, b= 60 cm, h= 40 cm

Therefore, area= 2(80 x 60+60 x 40+40 x 80) cm2

= 2(4800+2400+3200) cm2

= 2 x 10400 cm2

=20800 cm2

20800sq. cm of cloth is required to cover the box
