Introduction
Problem-solving challenges test your ability to analyze information, think logically, and make decisions based on given conditions. Try solving each challenge before checking the answer.
Question 1
A farmer has 10 chickens, 5 cows, and 2 horses.
How many legs are there in total?
A) 48
B) 50
C) 58
D) 60
Answer
C) 58
Explanation
10 chickens × 2 legs = 20
5 cows × 4 legs = 20
2 horses × 4 legs = 8
Total = 20 + 20 + 8 = 58
Question 2
A shopkeeper buys a pen for ₹20 and sells it for ₹25.
What is the profit percentage?
A) 20%
B) 25%
C) 30%
D) 40%
Answer

Profit = ₹25 − ₹20 = ₹5
Profit % = (5 ÷ 20) × 100
= 25%
Question 3
You have a 5-litre bucket and a 3-litre bucket.

Practice Tip
Always identify:
What information is given
What is being asked
Which formula or logic applies
This simple approach improves problem-solving accuracy.
