34 should be in place of 30. - Find the present age of Varun.

**Statement I:**Present age of Varun is 25% less than the present age of Vinit. Difference in the present ages of Varun and Vinit is 10 years.

**Statement II:**Present ages of Varun and Vinit are in the ratio 3:4 resp. Varun is 10 years younger than Vinit.I alone.Both I and II.Either I or II.II alone.Neither I nor II.Option C

From I:

Let the present age of Vinit be x years.

Present age of Varun = 0.75x years

Now, x – 0.75x = 10

=> x = 40

Present age of Varun = 0.75*40 = 30 years

I alone is sufficient.

From II:

Let the present ages of Varun and Vinit be 3x years and 4x years resp.

4x – 3x = 10

=> x = 10

II alone is sufficient.

Either I or II. - Find the length of the Shatabdi express.

**Statement I:**Shatabdi express can cross a pole and a platform 216 m long in 9 seconds and 17 seconds resp.

**Statement II:**Shatabdi express moving with a speed of 27 m/s can cross a man standing on platform in 9 seconds.Either I or II.II alone.Neither I nor II.I alone.Both I and II.Option A

From I:

Let the length of the train be x m.

Now, x/9 = (x+216)/17

=> x = 243

I alone is sufficient.

From II:

Length of train = 27*9 = 243 m

II alone is sufficient.

Either I or II. - A bag contains red, blue and green balls in the ratio 7:4:10 resp. Find the number of balls in the bag.

**Statement I:**Probability of drawing a red ball from the bag is 1/3.

**Statement II:**Two balls are randomly drawn from the bag and the probability that a red and a green ball are drawn is 1/3.Neither I nor II.II alone.Both I and II.Either I or II.I alone.Option B

From I:

Probability of red ball from the bag = 7C1/21C1 = 1/3

I alone is not sufficient.

From II:

Probability of a red and a green ball from the bag = (7C1*10C1)/21C2 = 1/3

(2*7x*10x)/21*(21x-1) = 1/3

=> x = 1

So, the number of balls in the bag = 7+4+10 = 21

II alone is sufficient. - There are five consecutive odd numbers. Find the second largest odd number.

**Statement I:**Largest odd number is three less than twice the smallest odd number.

**Statement II:**Largest odd number is eight more than the smallest odd number.I alone.Both I and II.Neither I nor II.II alone.Either I or II.Option A

From I:

Let the five consecutive odd numbers are (2x+1),(2x+3),(2x+5),(2x+7) and (2x+9)

2*(2x+1) – 3 = 2x + 9

=> x = 5

second largest odd number = 2*5+7 = 17

I alone is sufficient.

From II:

Let the five consecutive odd numbers are (2x+1),(2x+3),(2x+5),(2x+7) and (2x+9)

2x+9 – (2x+1) = 8

=> 8 = 8

II alone is not sufficient. - Gopal invested Rs.x in a scheme offering simple interest. Find the value of x.

**Statement I:**Interest earned by Gopal after three years is Rs. 1800.

**Statement II:**Interest earned by Gopal after seven years is Rs. 4200.Both I and II.Either I or II.I alone.Neither I nor II.II alone.Option D

From I:

Let the rate of interest be y%.

Interest earned after three years = (x*3*y)/100 = 1800

=> xy = 60000 I alone is not sufficient.

From II:

Let the rate of interest be y%.

Interest earned after seven years = (x*7*y)/100 = 4200

=> xy = 60000

II alone is not sufficient.

Combining I and II, Not sufficient.

**Directions(6-10):** Compare statement I and statement II and choose a required answer.
