Answers:

1. Answer: (b)

Let the original speed of the train be x kmph. ∴ Original time = 400/x h

New speed of train = (x + 10) kmph and

new time required = 400/(x +10 ) h

According to question, 400/x- 400/(x+10) =2

x² + 10x – 2000 = 0

x = 40 and –50

Disregarding the negative value, required original speed of train = 40 kmph

2. Answer: (c)

Let Ram’s and Shyam’s investment in the business be  4x and 3x, respectively.

Total profit = y

Profit distributed among Ram and Shyam = 90/100xy= 9y/10

Shyam’s share in the profit = 3/7x9y /10  = 2700

y = 7000

3. Answer: (a)

Let the first part of the number be x and the second part be (212 – x).

According to the question,

Second part of the number is (212 – 104) = 108

4. Answer: (b)

2/ 5 = 0.4, 3 /7 =0.42, 4 /11 = 0.36, 5 /13 = 0.38 and 9 /17 = 0.52.

Hence, the greatest fraction = 9 /17 .

5. Answer: (b)

Probability for Prakash to fail in the exam = 1 – 0.88 = 0.12

P( AUB) = P(A) + P(B) – P (A∩B)

Required probability = 0.15 + 0.12 – 0.15 × 0.12 = 0.252

6. Answer: (d)

Let S.P. of 1 article = 1

S.P. of 20 articles =  20

Profit = S.P. of 4 articles = 4

C.P. of 20 articles = 20 – 4 = 16

Profit percentage = 4 /16 x100 = 25%

7. Answer: (b)

20% of the total cost of plot =  78,210

10% of the total cost of plot =  39,105

Total cost of plot = 39105 × 10 = 3,91,050

Rate per square feet of plot = 391050/395 = 990

8. Answer: (b)

Let the number added to each term of the ratio be x. According to the given condition,

(21+x) /(16+ x)=5/ 4

84 + 4x = 80 + 5x

x = 4

9. Answer: (a)

Let the ages of 5 children be (x – 6), (x – 3), x, (x + 3) and (x + 6) years.

Therefore, x – 6 + x – 3 + x + x + 3 + x + 6 = 65

x = 13

So, the age of the youngest child = x – 6 = 13 – 6 = 7 years

10. Answer: (c)

Let the two numbers be a and b.

So according to the given condition, a + b = 14 and a – b = 28

a = 21 and b = –7.

And hence the required product = –147.
