Question

How to calculate coordination number for "inner" transition metals in a complex compound?

Answer 1

Correct Option: D

According to the formula .

Percentage of students passed in both the subjects  

= [100 - (x + y - z)]%

= [100 - (49 + 36 - 15)]% = 30%

Let total number of students = N  

According to the question,

(N x 30)/100 = 450

⇒ N = (450/30) x 100 = 1500

∴ Total number of students = 1500
