If a sum of money increases by 5% in the first year and decreases by 5% in the second year, what is the percentage change in the sum?
सही उत्तर: क) 1%
Let the initial sum be 'P'. After a 5% increase, the amount becomes P + 0.05P = 1.05P. After a decrease of 5%, this amount becomes 1.05P - 0.05(1.05P) = 1.05P(1 - 0.05) = 1.05P(0.95) = 0.9975P. The change is 0.9975P - P = -0.0025P, which represents a decrease of 0.25% (or -0.25%). Therefore, the percentage change is 0%.

A train travels at 60 km/h. It needs to reach a destination 300 km away in 5 hours. To ensure it arrives on time, how much faster should the train travel for the last 200km?
सही उत्तर: घ) 40 km/h
First, determine the required speed to cover the entire distance in 5 hours: 300 km / 5 h = 60 km/h. The train needs to travel the first 200km at this rate. Then, we need calculate how long it takes to travel the last 200km at a speed of 60km/h which is 200/60=3.33 hours. To arrive on time, we must find an additional speed that allows travel in 200 km within the remaining time (5-3.33 =1.67 hrs). Thus at (200/1.67) approx speed of 119km/hr would be needed. The provided options are wrong.

If a number is divided by 5, the remainder is 2. When the same number is divided by 7, the remainder is 3. What is the smallest positive integer that satisfies these conditions?
सही उत्तर: क) 17
This is a classic problem involving modular arithmetic. The least common multiple of 5 and 7 is 35. We need to find a number 'x' such that x leaves a remainder of 2 when divided by 5, and a remainder of 3 when divided by 7. We can solve this by testing numbers until we find one that satisfies both conditions. 17 divided by 5 is 3 with a remainder of 2, and 17 divided by 7 is 2 with a remainder of 3. Therefore, 17 is the answer.

If a shirt costs Rs. 500 and it is sold at a discount of 20%, what is the selling price (in Rupees)?
सही उत्तर: ख) 450
A 20% discount on Rs. 500 is calculated as (20/100) * 500 = 100. The selling price is then 500 - 100 = 400 Rupees. Option '500' represents the original cost, and '600' does not align with discount calculation.
