Q1. Two trains A and B start from stations P and Q, which are 60 km apart, and travel towards each other. Train A travels at a speed of 40 km/hr and Train B travels at a speed of 20 km/hr. They meet at a point R between P and Q. Find the distance from Q to point R.

Sample Answer: Let “t” be the time taken for both trains to meet at point “R”. 

Distance covered by Train A: 40t 

Distance covered by Train B: 20t 

Since Train B starts from Q and has travelled the distance to P, the total distance covered by Train B will be 20t + 60 

Since both trains meet at point R, the distance covered by both trains is equal: 

40t = 20t + 60 

40t – 20t = 60 

20t = 60 

t = 3 

Distance QR = 20t = 20×3 = 60 km

Q2. Person A can complete a task in 4 hours. When persons B and C work together, they can finish the task in 3 hours, and when persons A and C work together, they can complete it in 2 hours. What is the time it takes for person B alone to complete the task?

Sample Answer:  A’s 1 hour work = ¼

(B + C)’s 1-hour work = ⅓

(A + C)’s 1-hour work =½

(A + B + C)’s 1 hour work = ( ¼ + ⅓) = 7/12 

B’s 1-hour work =(  7/12 + ½) = 1/12 

B alone will take 12 hours to do the work.

Q3. A shopkeeper sells an item at a 20% profit. If he had bought it for 20% less and sold it for ₹20 less, he would have gained 25%. Find the cost price of the item.

Sample Answer: Let the cost price be x

• Selling price (at 20% profit): 1.2x
• New cost price (20% less): 0.8x
• New selling price (₹20 less): 1.2x – 20

According to the question: 

1.2x − 20 = 0.8x × 1.25 

1.2x − 20 = x

0.2x = 20

X = 100 

The cost price of the item is ₹100.
