Step-by-step explanation:
<u>Here :-</u>
- Selling price of 25 balls is equal to the Cost of 15 balls
<u>Let the cost price of one ball is ₹1. So ;-</u>
- Cost price of 25 balls = ₹25
- Cost price of 15 balls = ₹15
↝ Here the selling price of 25 balls is equal to the cost of 15 balls. It means C.P of 15 balls = S.P of 25 balls. So, the selling price of 25 balls is ₹15.
<u>Firstly, finding the loss :-</u>
<em><u>∴ The loss is Rs.10.</u></em>
<u>Now, finding the loss percentage :-</u>

Step-by-step explanation:
Hope this helps :)
Let’s assume the following given:
Speed = 129 m/s
Time = 2,900,000 s
Find:
Distance = ?
Solution:
In order to get the distance, we multiply speed and time.
Distance = Speed * Time
Distance = 129 m/s * 2,900,000 s
Distance = 374,100,000 m
Next, we will convert the distance from meters to kilometers
by dividing the distance with 1,000 m.
374,100,000 m / 1,000 m = 374,100 km
<span>The last step would be converting the travelled distance in
kilometers to the nearest ten thousand.
Therefore, the travelled distance in kilometers to the nearest ten thousand is
370,000 km.</span>
