Given:
The ratio of coins of 2 rupees, 1 rupees and 50 paise = 3 : 4 : 5
Calculation:
The ratio of value (price) of 2 rupees, 1 rupees and 50 paise = (2 × 3) : 4 : (5/2) = 6 : 4 : 5/2
⇒12 : 8 : 5
The ratio of value (price) of 2 rupees, 1 rupees and 50 paise = 12x : 8x : 5x
According to the question
12x + 8x + 5x = 250
⇒ 25x = 250
⇒ x = 250/25
⇒ x = 10
Value (price) of 1 rupees coins = 8 × 10 = 80
Therefore, the correct answer is 80.
