The answer is, 352

 

Directions (Q. 6 – 10):

  1. Answer c

(888/12) + (2756/13) + (1472/16) = (x/100)*720

74 + 212 + 92 = (x/100)*720

378 = (x/100)*720

X = (378*100) /720

X = 52.5

  1. Answer d

15120 / 1512 = x

X = 10

  1. Answer a

225 – 1156 + (8700/x) = 229

(8700/x) = 229 – 225 + 1156

(8700/x) = 1160

X = 8700/1160

X = 7.5

  1. Answer d

(3/18) * 2286 + (2/11) * 2431 = x

X = 381 + 442

X = 823

  1. Answer b

92 × (15 * 15)/ 25 = 9x

9x = 9 × 92

9x = 93

X = 3

 

  1. Answer a

A + B + C = Rs. 16400

(2/15)* A = (3/5)* B

(A/B) = (3/5) * (15/2) = 9/2

(3/4)* B = (9/16)* C

(B/C) = (9/16) * (4/3) = ¾

 

41’s = 16400

1’s = 400

27’s = 10800

  1. Answer d

The ratio of share of P, Q and R

= > [60000*5 + 60000*(70/100)*7]: [70000*5 +85000*7] : [80000*8 + 80000*(80/100)*4]

= > 594000 : 945000 : 896000

= > 594 : 945 : 896

2435’s = Rs. 58440

1’s = 24

Q’s share = 945*24 = Rs. 22680

  1. Answer b

5 years ago, Anu : Hema = 6 : 5(6x , 5x)

Present ages of Anu and Hema = 6x + 5, 5x + 5

Three years ago, Anu’s age is equal to Hema’s age after 2 years,

= > 6x +2 = 5x + 7

= > x = 5

Present age of Anu = 6x + 5 = 35 years

  1. Answer c

(x – 5)/20 + x/25 = 1

(5x – 25 + 4x)/100 = 1

9x – 25 = 100

9x = 125

X = 125/9 = 13 8/9 days

  1. Answer a

Length – Breadth = 16

Length = Side of square

Area of square = 1024 = a2

Side (a) = 32 m = length

According to the question,

32 – b = 16

Breadth = 32-16 = 16 m

Perimeter of the rectangle = 2(l + b) = 2(32 + 16)

= > 2(48)

= > 96 m

 

Directions (Q. 16 – 20):

  1. Answer b

Let the Income of Company A in 2004 and expenditure of company A in 2007 be x,

Expenditure of Company A in 2004

= > x = exp*(140/100)

= > exp = 100x/140

Required ratio = (100x/140) : x = 5 : 7

  1. Answer e

Income of company A in year 2006 = 4/5 x 21.5 = Rs. 17.2 lakh

If expenditure of company A in year 2006 is Rs. X

Profit % = {(I – E)/E} *100

Then, 65 = [17.2-x/x]*100

=> x = 1720/165 = Rs. 10 Lakh (Approx.)

  1. Answer b

Expenditure of Company B = 2 x 15/5 = Rs. 6 lakh

If income of company B in year 2006 is Rs. x, then

50 = {(x-6)/6}*100

x = Rs. 9 lakh

  1. Answer c

Let the Income of Company A in 2003 and expenditure of company B in 2004 be x,

Expenditure of Company A in 2003

= > x = exp*(140/100)

= > exp = 100x/140

Income of Company B in 2004

= > Inc = x*(150/100)

Ratio = 100x /140 : 150x /100 = 10 : 21
