Verified Answer
A person has 45 coins of 50p, 1 rupee and 2 rupee coins in ratio 6 : 2...
Actual money with the person = 0.5((6/9) × 45) + 1((2/9) × 45) + 2((1/9) × 45) = 15 + 10 + 10 = Rs. 35
Total money in First case:
Total value of coins = 0.25((6/9) × 45) + 0.50((2/9) × 45) + 1((2/9) × 45) = 7.5 + 5 + 10 = Rs. 22.50
Total money in Second case:
Total value of coins = 0.25((6/9) × 90) + 0.50((2/9) × 90) + 1((2/9) × 90) = Rs. 45
Total money in Third case:
Total value of coins = 0.25((6/14) × 70) + 0.50((5/14) × 70) + 1((3/14) × 70) = Rs. 35
In third case, the amount is same

A person has 45 coins of 50p, 1 rupee and 2 rupee coins in ratio 6 : 2...
Explanation:
Given information:
- The person has 45 coins in total, consisting of 50p, 1 rupee, and 2 rupee coins.
- The coins are in the ratio 6 : 2 : 1.
Calculation:
- Let the number of 50p coins be 6x, 1 rupee coins be 2x, and 2 rupee coins be x.
- Total number of coins = 6x + 2x + x = 9x = 45
- x = 5
Calculating total money for each case:
- Total money in the first case = 6(0.50) + 2(1) + 1(2) = 3 + 2 + 2 = 7
- Total money in the second case = 6(0.50) + 2(1) + 1(2) = 3 + 2 + 2 = 7
- Total money in the third case = 6(0.50) + 5(1) + 3(2) = 3 + 5 + 6 = 14
Conclusion:
- The combination that yields the same total money is option C: 6, 5, 3, 70.
