Arithmetic Questions for SBI PO Exam 2025

Here are some new Arithmetic Questions with solutions to help you excel in the SBI PO Exam.

1. Time and Work

A and B together can complete a task in 8 days. B and C can finish it in 10 days, while C and A together can complete it in 12 days. If all three work together, how many days will they take to complete the task?
(a) 6
(b) 5
(c) 4
(d) 7
(e) None of these

Solution:
Let the total work = LCM of 8, 10, and 12 = 120 units.

  • A + B’s 1-day work = 120/8 = 15 units.
  • B + C’s 1-day work = 120/10 = 12 units.
  • C + A’s 1-day work = 120/12 = 10 units.

Adding all, 2(A + B + C)’s 1-day work = 15 + 12 + 10 = 37 units.
=> A + B + C’s 1-day work = 37/2 = 18.5 units.

Time taken = Total work / Work per day = 120 / 18.5 ≈ 6.5 days.
Answer: (e) None of these

2. Profit and Loss

An article is sold at a 15% profit after giving a 10% discount on its marked price. If the cost price of the article is Rs. 450, find its marked price.
(a) Rs. 600
(b) Rs. 575
(c) Rs. 540
(d) Rs. 525
(e) None of these

Solution:
Selling price = Cost price × (1 + Profit%) = 450 × 1.15 = Rs. 517.5.

Marked price = Selling price / (1 – Discount%) = 517.5 / 0.9 = Rs. 575.
Answer: (b) Rs. 575

3. Speed and Distance

A train running at a speed of 72 kmph crosses a pole in 25 seconds. Find the length of the train.
(a) 450 meters
(b) 500 meters
(c) 525 meters
(d) 600 meters
(e) None of these

Solution:
Speed = 72 kmph = (72 × 1000) / 3600 = 20 m/s.
Length of the train = Speed × Time = 20 × 25 = 500 meters.
Answer: (b) 500 meters

4. Simple Interest

A sum of Rs. 12,000 is invested at a 10% per annum simple interest rate for 3 years. Find the total interest earned.
(a) Rs. 3,600
(b) Rs. 3,000
(c) Rs. 3,200
(d) Rs. 3,800
(e) None of these

Solution:
Interest = Principal × Rate × Time / 100 = 12,000 × 10 × 3 / 100 = Rs. 3,600.
Answer: (a) Rs. 3,600

5. Average

The average of five numbers is 68. If one of the numbers is excluded, the average of the remaining four numbers becomes 72. Find the excluded number.
(a) 52
(b) 56
(c) 64
(d) 60
(e) None of these

Solution:
Sum of five numbers = 68 × 5 = 340.
Sum of four numbers = 72 × 4 = 288.
Excluded number = 340 – 288 = 52.
Answer: (a) 52

6. Ratio and Proportion

The ratio of the present ages of A and B is 4:5. Five years ago, the ratio of their ages was 3:4. Find the present age of A.
(a) 20 years
(b) 24 years
(c) 30 years
(d) 32 years
(e) None of these

Solution:
Let present ages of A and B be 4x and 5x, respectively.
Five years ago:
(4x – 5)/(5x – 5) = 3/4.

Cross-multiply:
16x – 20 = 15x – 15
x = 5.

Present age of A = 4x = 4 × 5 = 20 years.
Answer: (a) 20 years

7. Pipes and Cisterns

Pipe A can fill a tank in 12 hours, and pipe B can fill it in 16 hours. Pipe C can empty the tank in 24 hours. If all three pipes are opened together, how long will it take to fill the tank?
(a) 8 hours
(b) 10 hours
(c) 6 hours
(d) 12 hours
(e) None of these

Solution:
Work done by A in 1 hour = 1/12, by B = 1/16, and by C = -1/24.
Net work done in 1 hour = 1/12 + 1/16 – 1/24 = (4 + 3 – 2)/48 = 5/48.

Time taken = 48/5 = 9.6 hours ≈ 10 hours.
Answer: (b) 10 hours
