Directions (Q. 6 – 10):

  1. Answer c

(25/9)*(2/11)*(693/350) = (1/3)*(5/7)*(147/175)*x

1 = (x/5)

X = 5

  1. Answer d

1134 ÷ [(3/7)*91 – 21] = x

1134 ÷ [39 – 21] = x

1134/18 = x

X = 63

  1. Answer b

(913 + 329 + 522 + 343) ÷ (18 + 24 – x + 18) = 43

2107 ÷ (60 –x) = 43

(2107/43) = 60 – x

49 = 60 – x

X = 60 – 49 = 11

  1. Answer a

5x = 59 × 25 ÷ 55 × (55)2

5x = 59 × 52 ÷ 55 × 510

5x = 59 +2 – 5 +10

5x = 516

X = 16

  1. Answer d

(3/7)*x – (2/5)*(13/16)*2160 = (12/100)*900

(3x/7) – 702 = 108

(3x/7) = 108 + 702

(3x/7) = 810

X = (810*7/3) = 1890

 

  1. Answer b

Let the prices of the refrigerators were 11x and 13x respectively.

According to the question

(11x * 120/100)/(13x + 500) = 44/45

=> (3x/10)/(13x+500) = 1/45

=> 3x/10*45 = 13x+500

=> 27x = 26x +1000

=> x= 1000

=> x = 1000

Required sum = 11x+ 13x = 24x = 24 *1000= Rs. 24000

  1. Answer a

Three pipes A, B and C can fill a tank in 12 hours.

A, B and C’s 1 hour work=1/12

A, B and C’s 3 hour work= 3/12

Remaining work= 1- 1/4 =3/4

The remaining part will be filled by A and B in 6 hours. Then,

= > (3/4) *(A+B) = 15

= > (A+B)’s whole work= 20 hr

(A+B)’s 1 hour work= 1/20

A, B and C’s 1 hour work=1/12

C’s 1 hour work= (A+B+C)-(A+B)

= > (1/12) – (1/20)

= > 1/30

C can fill the tank in 30 hours.

  1. Answer c

Five years hence, the ratio of Jeevitha and Janvi = 5:3(5x, 3x)

According to the question,

5x + 5 = 3*(3x – 5)

5x + 5 = 9x – 15

4x = 20

X = 5

The present age of Jeevitha = 5x – 5 = 25 – 5 = 20 years

  1. Answer a

The share of A, B and C

= > [4500*7 + 4500*(140/100)*5]: [5600*7 + 5600*(125/100)*5]: [7500*4 + 7500*(120/100)*8]

= > 63000: 74200: 102000

= > 315: 371: 510

1196’s = 53820

1’s = 45

The share of C = Rs. 22950

  1. Answer d

Let the cost price be x,

MP = (130/100)*x = (13x/10)

SP = (13x/10)*(80/100) = (26x/25)

Profit = SP – CP

(26x/25) – x = 300

26x – 25x = 300*25

X = 7500

Cost price of bed = Rs. 7500

 

Directions (Q. 16 – 20)

  1. Answer a

The total number of Q type tiles manufactured in the year 2014 = 12000

The total price per tiles of Q type tiles manufactured in the year 2014 = Rs. 290

Total cost of Q type tiles in the year 2014 = 12000*290 = 3480000

The total number of Q type tiles manufactured in the year 2016 = 17000

The total price per tiles of Q type tiles manufactured in the year 2016 = Rs. 300

Total cost of Q type tiles in the year 2016 = 17000*300 = 5100000

Required % = [(5100000 – 3480000)/5100000]*100

= > 31.76 % = 32 % less

  1. Answer d

Total price per tiles of P type tiles of all the given years together

= > 240 + 260 + 220 + 270 + 200 + 225

= > 1415

Total price per tiles of R type tiles of all the given years together

= > 320 + 360 + 350 + 380 + 275 + 370

= > 2055

Required % = (1415/2055)*100 = 68.85 % = 69 %

  1. Answer c

The total price per tiles of S type tiles in the year 2013, 2015 and 2017 together

= > [320 + 340 + 390]

= > 1050

The total price per tiles of Q type tiles in the year 2012, 2014 and 2016 together

= > [280 + 290 + 300]

= > 870

Required difference = 1050 – 870 = 180

  1. Answer b

The total price per tiles of all the given tiles together in the year 2014 and 2016

= > [350 + 330 + 290 + 220 + 200 + 275 + 300 + 325]

= > 2290

The total price per tiles of all the given tiles together in the year 2015 and 2017

= > [270 + 320 + 340 + 380 + 225 + 310 + 370 + 390]

= > 2605

Required ratio = 2290: 2605 = 458: 521

  1. Answer c

The total number of R type tiles manufactured in the year 2013 = 17000

Total revenue of R tiles in the year 2013

= > 17000*360 = 6120000

The total number of R type tiles manufactured in the year 2016 = 11000

Total revenue of R tiles in the year 2016

= > 11000*275 = 3025000

Required average = (6120000 + 3025000)/2

= > 4572500
