  1. Answer a

Explanation:

The pattern is, ÷2 – 0.5

The answer is, 10.25

  1. Answer e

Explanation:

(64 × 64 × 4 × 26 × 26) / (211 × 13 × 13) = 2x

(26 × 26 × 24)/ 211 = 2x

26+6+4 -11 = 2x

25 = 2x

X=5

  1. Answer d

Explanation:

(3/8) × 111 = x/2

42*2 = x

X= 84

  1. Answer b

Explanation:

(25/100)*400 ÷ x = ((125/100) * 4)2

100/x = 52

100/25 = x

X = 4

  1. Answer d

Explanation:

√x = (1300/100) – 8

√x = 13 -8 =5

X= 25

  1. Answer a

Explanation:

(79/100)*790 – (13/100)*3280 = x

79 * 7.9 – 13*33 = x

632 – 429 =x

X= 203~200

11.Answer c

Explanation:

Marked Price = Rs. 2675

Profit = 7%, Discount = 15%

SP = MP*(85/100)

SP = CP* (107/100)

2675 *(85/100) = CP* (107/100)

CP = 2125

  1. Answer b

Explanation:

Investment ratio = 6:7

Profits = 3:5, A has invested for 7 months.

Ratio of Profit = 6*7: 7*x = 42: 7x

According to the question,

42/7x = 3/5

X = 10 months

13.Answer d

Explanation:

Let original fraction be x/y.

(X*130/100) / (y*25/100) = 21/25

x/y = (21/25)*(25/130)

x/y = 21/130

  1. Answer b

Explanation:

Present age of Vinay = Ragu’s age 8 years ago

4 years hence, Vinay: Ragu = 4:5 (4x, 5x)

Present ages will be, 4x-4, 5x-4

According to the question,

4x-4 = 5x-4-8

X=8

Present age of Vinay = 4x-4 = 32-4 =28 years

  1. Answer b

Explanation:

Total work = (men (or) women)*days

Work equal, so,

(5 w + 6 m)*8 = (4 w + 9 m)*6

40 w + 48 m = 24 w + 54 m

16 w= 6 m

8 w = 3 m

1 w = (3/8) m

4 w + 9 m = 4*(3/8) m+ 9 m = (21/ 2) m

8 w + 9 m = 3 m + 9 m = 12 m

Men            days

(21/2)                   6

12               ?

(21/2)*6 = 12x

X= 21/4 days = 5 ¼ days
