Let's break the problem down step by step:

1. Let the total value of Surendra's property be $x$.

2. He gives 60% of his property to his wife.
   This means the remaining property is: $\text{Remaining property} = 100\% - 60\% = 40\% \text{ of } x$ So, the remaining property is $0.4x$.

3. He gives 75% of the remaining property to his daughter.
   This means the amount given to his daughter is: $\text{Daughter's share} = 75\% \text{ of } 0.4x = 0.75 \times 0.4x = 0.3x$

4. The rest is given to a trust.
   The amount left for the trust is: $\text{Trust's share} = 25\% \text{ of } 0.4x = 0.25 \times 0.4x = 0.1x$ According to the problem, Surendra gives Rs. 6,00,000 to the trust. Therefore: $0.1x = 6,00,000$

5. Now, solve for $x$: $x = \frac{6,00,000}{0.1} = 60,00,000$ So, the total value of Surendra's property is Rs. 60,00,000.

6. Find the share given to his daughter:
   We know the daughter receives $0.3x$. Therefore, the daughter's share is: $\text{Daughter's share} = 0.3 \times 60,00,000 = 18,00,000$

Answer: The worth of the share of the property given to his daughter is Rs. 18,00,000.
