AFCAT I 23 Jan 2025 Shift 2 Paper

We know that the value ratio of 1 rupee, 50 paise and 25 paise is 1:1∕2:1∕4
In those 465 coins their amount ratio is 5:3:1
Let the common multiple is x
So according to the question,
‌5x+6x+4x=465
‌⇒15x=465
‌⇒x=31
So in those 465 coins,
1 rupee coin value =(31×5)= Rs. 155
50 paise coin value =(31×3)= Rs. 93
25 paise coin value =(31×1)= Rs. 31
So 1 rupee coin was (155×1)=155
50 paise coin was (93×2)=186
25 paise coin was (31×4)=124
