**Practice Quantitative Aptitude Questions for IBPS RRB OA:**

**1. The ratio between the speeds of two trains is 6: 8. If the second train runs 500 km in 5 hours, then the speed of the first train is:**

A. 85 km/h

B. 60 km/h

C. 80 km/h

D. 75 km/h

**Answer: D**

**Explanation:**

Let the speed of two trains be 6x and 8x km/hr

Then, 8x = 500 / 5 = 100

x = 100 / 8 = 12.5

Speed of first train = (6 x 12.5) km/h = 75 km/h

**2. Factorize the Algebraic Expression (P - 2)2 - (Q - 3)2?**

A. (Q - P + 1) (P + Q - 5)

B. (P - Q + 3) (P + Q - 1)

C. (P - Q + 1) (P + Q - 5)

D. (Q - P + 3) (P + Q - 3)

**Answer: C**

**Explanation:**

(A - B) (A + B) = A2 - B2

Where, A = (P - 2), B = (Q - 3)

(P - 2)2 - (Q - 3)2 = ((P - 2) - (Q - 3)) ((P - 2) + (Q - 3))

= (P - 2 - Q + 3) (P - 2 + Q - 3)

= (P - Q + 1) (P + Q - 5)

**3. In a fruit box, there are 8 Apples, 7 Mangoes, and 6 Oranges. One Fruit is picked up randomly. What is the probability that it is neither Apples nor Oranges?**

A. 2 / 3

B. 1 / 3

C. 3 / 4

D. 1 / 2

**Answer: B**

**Explanation:**

Total number of Fruits n(S) = (8 + 7 + 6) = 21.

Let E → the event that the Fruit is picked neither Apple nor Orange

Let P(E) → event that the Fruit is picked Mango.

n(E) = 7

P(E) = n(E) / n(S) = 7/21 = 1 / 3

**4. Out of 9 consonants and 4 vowels, how many words of 5 consonants and 2 vowels can be formed?**

A.835

B.536

C.756

D.652

**Answer: C**

**Explanation:**

= Number of ways of selecting (5 consonants out of 9) and (2 vowels out of 4)

= (9C5 x 4C2)

=[(9 * 8 * 7 * 6 * 5) / ( 5* 4 * 3 * 2 * 1)] * (4 * 3 / 2 * 1)

= 756 ways

**5. In how many ways can a group of 6 men and 3 women be formed from 7 men and 4 women?**

A. 28

B. 32

C. 36

D. 42

**Answer: A**

**Explanation:**

We need to select 6 men from 7 men and 3 women from 4 women.

= Number of ways to do this

= 7C6 × 4C3

= 7C1 × 4C1 [ nCr = nC(n-r)]

= 7× 4 = 28

**6. Given an arithmetic progression with the initial term 5 and the common difference 7. What is the 10th term?**

A. 54

B. 85

C. 76

D. 68

**Answer: D**

**Explanation:**

If a = 5 and the common difference is d = 7 by the formula above, we have

T10 = 5 + [(10 -1)7] [Using arithmetic progression Tn = a + (n - 1)d ]

= 5 + 63 = 68

Thus, the 10 term in the arithmetic progression is 68.

**7. Find the value of x from the following expression:**

**[- 2 ( x - 3 )] + [4 ( - 2x + 8)] = 0**

A. 4

B. 8

C. 3

D. 2

**Answer: A**

**Explanation:**

→ [- 2 ( x - 3 )] + [4 ( - 2x + 8)] = 0

→ - 2x + 6 - 8x + 32 = 0

→ - 10x + 40 = 0

→ x = 4

**8. What is the probability of getting a sum 7 from two throws of a dice?**

A. 1/9

B. 1/8

C. 1/7

D. 1/6

**Answer: D**

**Explanation:**

In two throws of a dice, n(S) = (6 x 6) = 36.

Let E → event of getting a sum ={(1, 6), (4, 3), (3, 4), (6, 1), (2,5), (5,2)}.

→ P(E) = n(E) / n(S)

→ 6/36 = 1/6

**9. Which of the following cannot represent probability?**

A. 0

B. -0.01

C. 0.5

D. 1

**Answer: B**

**Explanation:**

A probability is always greater than or equal to 0 and less than or equal to 1, hence only B cannot represent probability: -0.01,i.e., less than 0.
