Aspirants preparing for IBPS PO Prelims 2022 need to focus on mastering Quantitative Aptitude, a crucial section in the exam. Here is a curated list of sample questions with detailed solutions to help you ace this section:
Question 1:
A retailer marked the price of a shirt 20% above the cost price and offered a discount of 10%. If the selling price of the shirt is ₹720, find the cost price.
Solution:
Let the cost price be x. Selling price after a 10% discount = 90% of marked price = ₹720. Therefore, 90% of (120% of x) = 720.
Question 2:
If x² – 3x – 18 = 0, find the value of (x + 2)(x – 5).
Solution:
Factorize x² – 3x – 18 = (x – 6)(x + 3). So, (x + 2)(x – 5) = (x – 6)(x + 3) = 0.
Question 3:
The ratio of the present ages of P and Q is 4:5. If the sum of their present ages is 54 years, find their ages.
Solution:
Let the ages of P and Q be 4x and 5x respectively. So, 4x + 5x = 54. Therefore, P’s age = 4 * 6 = 24 years, and Q’s age = 5 * 6 = 30 years.
