Since the ratio between the numbers of coins of 20p, 10p and 5p is 1 : 2 : 3 So let us assume the number of 20p coins = a

Then number of 10p coins is 2a and number of 5p coins is 3a.
Total worth of 20p coins = number of coins X worth of each coin = a X (1/5) = Rs (a/5)
Total worth of 10p coins = 2a X (1/10) = Rs (a/5)
Similarly total worth of 5p coins = 3a X (1/20) = Rs (3a/20)
Since total money with the Divya is Rs 44 hence
a/5 + a/5 + 3a/20 = 44 => 2a/5 + 3a/20 = 44
=> 8a/20 + 3a/20=44 => 11a/20 =44 => a = 80
So the number of 5p coins = 3a = 80 x 3 = 240

Given Information:
- Denominations: 20p, 10p, 5p
- Ratio of coins: 1:2:3
- Total money: Rs. 44
Solution:
Step 1: Express the ratio in terms of total value
- Let the common ratio be x.
- So, the total value of coins in the ratio 1:2:3 is 20x, 10x, and 5x respectively.
Step 2: Calculate the total value of the coins
- Total value = 20x + 10x + 5x = 44
- 35x = 44
- x = 44/35 = 1.26
Step 3: Find the number of 5p coins
- Number of 5p coins = 3 * 1.26 = 3.78
- Since we cannot have a fraction of a coin, we need to consider the nearest whole number.
- Therefore, the number of 5p coins = 3 (as it is the nearest whole number to 3.78)
Therefore, Divya has 240 (3 * 80) 5p coins. So, option (a) is the correct answer.
- Denominations: 20p, 10p, 5p
- Ratio of coins: 1:2:3
- Total money: Rs. 44
Solution:
Step 1: Express the ratio in terms of total value
- Let the common ratio be x.
- So, the total value of coins in the ratio 1:2:3 is 20x, 10x, and 5x respectively.
Step 2: Calculate the total value of the coins
- Total value = 20x + 10x + 5x = 44
- 35x = 44
- x = 44/35 = 1.26
Step 3: Find the number of 5p coins
- Number of 5p coins = 3 * 1.26 = 3.78
- Since we cannot have a fraction of a coin, we need to consider the nearest whole number.
- Therefore, the number of 5p coins = 3 (as it is the nearest whole number to 3.78)
Therefore, Divya has 240 (3 * 80) 5p coins. So, option (a) is the correct answer.
