Q3. Points A, B, C, and D lie on the same straight line. B, C, and D are 200 m, 300 m, and 500 m away from A respectively. Anshu and Ravi leave A at the same time and run towards D. Simultaneously, Sindhu leaves D and runs towards A. Sindhu meets Anshu at C and Ravi at B. If each person is running at a uniform speed, what is the distance between A and C?

Study Notes
Mathematics Problems Overview
- Problem 1 involves determining the number of boys in a class based on the relationship between the number of girls and boys and their respective average toffee distributions.
- Problem 2 discusses a scenario where Surekha allocates her budget at a vegetable market to buy potatoes and tomatoes, requiring a calculation of the quantity of tomatoes purchased.
- Problem 3 presents a geometry problem involving distance and uniform speed, where four points lie on a straight line, and two individuals run towards a meeting point.
- Problem 4 is a straightforward distribution query, calculating the number of toffees distributed among girls based on the known number of boys in the class.
- Problem 5 modifies the spending behavior of Surekha at the market, asking for recalculation of the tomatoes purchased when she spends a different percentage of her budget.
Problem 1 Details
- The number of girls exceeds boys by 15.
- Average toffees per girl are 2 less than per boy.
Problem 2 Details
- Surekha can initially purchase either 6 kg of tomatoes or 5 kg of potatoes.
- She decides to spend only 80% of her total money.
- The problem requires evaluating the quantity of tomatoes alongside the purchase of 3 kg of potatoes.
Problem 3 Details
- Points A, B, C, and D are collinear, with defined distances from A:
- B is 200 m away
- C is 300 m away
- D is 500 m away
- Anshu runs towards D and meets Sindhu at C; Ravi meets Sindhu at B.
- The problem seeks to find the distance between points A and C.
Problem 4 Details
- If the class contains 20 boys, the distribution of toffees among girls needs to be calculated based on the established relationship between boys and girls.
Problem 5 Details
- Surekha changes her spending to only 70% of her total budget.
- Analysis needed to determine the new quantity of tomatoes purchased given the updated budget.
