Number of students in class A is 120. Statement II- Number of students in class C is 80% of total number of students in class A and class B. Number of group X students in class A is 1/3rd of total number of students in class A. Total number of group X and group Y students in class B is 40. Statement III- Ratio of group Y and group Z students in class A is 3 : 1. Ratio of group X and group Y students in class B is 3 : 1. Total number of students in class B is 250% of total number of students of group X and group Y. Statement IV- Ratio of group X, group Y and group Z students in class C is 3 : 5 : 3 Number of students in class A is what % of number of students in class B?

Given below are assertion and reason. Point out if both are true with reason being correct explanation (A), both true but reason is not correct explanation (B), assertion true but reason is wrong ( C ), both are wrong (D). Assertion : Analogous organs are a result of divergent evolution Reason : Eye of Octopus and that of mammals depict divergent evolution.

Assertion: Claspers of certilage fishes are analogous to penis of human male Reason: Both act as copulatory organs and transfer the sperms into female

Assertion :- Analogous structures are a result of convergent evolution. Reason :- Different strutures evolving for the same function and hence having similarity.
