Answers :

1) Answer: B

x/y = (35 – 32)/(32 – 30) = 3/2

2) Answer: A

Let us take the number be x and quotient be y,

x = 42y + 10

= (6 * 7)y + 6 + 4

= 6 (7y + 1) + 4

Therefore, the number divided by 6 we get 4 as reminder.

(or)

Remainder on dividing by 42 = 10

Remainder on dividing the same number by 6 i.e 10/6 = 4 = Remainder

3) Answer: C

Ratio of the values of coins = 2: 3/2: 4/4 = 4: 3: 2

Sum = 4 + 3 + 2 = 9

Value of 25 paise coins = 2/9 * 270 = Rs.60

Number of 25 paise coins = 60 * 4 = Rs.240

4) Answer: B

PLANTS has 6 letters.

Number of ways A, N can be arranged 2! ways

Taking AN as 1 letter, then there are 5 letters.

Required nmber of ways = 5! * 2! = 240

5) Answer A

Ratio of Speeds, A: B = 126: 90 = 7: 5

Ratio of time, A: B = 5: 7

Difference between ratio of time = 7 – 5 = 2 (which is equal to given diff.)

Therefore, Distance = 126 × 5 = 90 × 7 = 630 Km

6) Answer: A

Required total = 200 + 150 + 250 + 100 = 700

7) Answer: B

Total number of boys like both games from Civil = 175 + 200 = 375

Total number of boys like both games from Automobile = 150 + 250 = 400

Difference = 400 – 375 = 25

8) Answer: D

Required total = 150 + 100 + 125 + 200 + 140 + 250 = 965

9) Answer: C

Required percentage = (160 + 140)/(250 + 125) * 100

= 80%

10) Answer: A

Required average = (250 + 200 + 250 + 160 + 150)/5 = 202
