divisor in equity

To calculate the value of the index after the split (at the end of Day 2) for stock Z, which completed a three-for-one split at the end of Day 1, you can follow these steps:

1. Calculate the price change factor for each stock:
   • For stock X, the price change factor is (Price after Split / Price before Split) = $12 / $10 = 1.2.
   • For stock Y, the price change factor is (Price after Split / Price before Split) = $19 / $20 = 0.95.
   • For stock N, the price change factor is (Price after Split / Price before Split) = $22 / $60 = 0.3667 (rounded to four decimal places).
2. Calculate the adjusted price for each stock at the end of Day 1 (after the split):
   • For stock X, the adjusted price is (Price before Split) * (Price change factor) = $10 * 1.2 = $12.
   • For stock Y, the adjusted price is (Price before Split) * (Price change factor) = $20 * 0.95 = $19.
   • For stock N, the adjusted price is (Price before Split) * (Price change factor) = $60 * 0.3667 = $22 (rounded to the nearest whole number).
3. Calculate the value of the index at the end of Day 1 by summing up the adjusted prices of all the stocks:
   • Index at the end of Day 1 = (Adjusted price of X) + (Adjusted price of Y) + (Adjusted price of N) = $12 + $19 + $22 = $53.
4. Calculate the value of the index at the end of Day 2 by using the same adjusted prices:
   • Index at the end of Day 2 = (Adjusted price of X) + (Adjusted price of Y) + (Adjusted price of N) = $12 + $19 + $22 = $53.

So, the value of the index after the split (at the end of Day 2) for stock Z is closest to $53. Therefore, the correct answer is not provided in the options you provided.
