Answer:
The number of 50 paise, 25 paise and 10 paise coins are 120, 180 and 240 respectively.
Step-by-step explanation:
Let the number of 50 paise, 25 paise and 10 paise coins be 2x, 3x and 4x respectively.
Given, Total amount = ₹ 129 = 12900p
By condition,
50 × 2x + 25 × 3x + 10 × 4x = 12900
=> 100x + 75x + 40x = 12900
=> 215x = 12900 => x = 12900/215
= 60
No of 50 paise coins = 2x = 2×60 = 120
No of 25 paise coins = 3x = 3×60 = 180
No of 10 paise coins = 4x = 4×60 = 240
