A bag contains 50 paise, 25 paise and 10 paise coins in the ratio 5 : ...
Given: Ratio of 50 paise, 25 paise, and 10 paise coins = 5 : 9 : 4
Total amount = Rs. 206

Let the common ratio be x.
Then, Number of 50 paise coins = 5x
Number of 25 paise coins = 9x
Number of 10 paise coins = 4x

Total amount can be calculated as:
(5x * 50 paise) + (9x * 25 paise) + (4x * 10 paise) = 206 * 100 paise
Simplifying this, we get:
250x + 225x + 40x = 20600
515x = 20600
x = 40

Therefore, Number of 50 paise coins = 5x = 200
Number of 25 paise coins = 9x = 360

The difference between the number of 50 paise and 25 paise coins is:
360 - 200 = 160

Hence, the answer is option A) 160.
