In each of these questions two equations numbered I and II are given. You have to solve both the equations and give answer, if –

I. 9/(4 )p + 7/8p = 21/12

II. 7/5p = 9/10q + 1/4

A p=q , Correct Answer Incorrect Answer
B p>q, Correct Answer Incorrect Answer
C p Correct Answer Incorrect Answer
D p≥q, Correct Answer Incorrect Answer
E p≤q Correct Answer Incorrect Answer

Solution

I.9/4p +7/8 p = 21/12 ⟹25/8 p = 25/12 ⟹p =2/3 II. 7/5 p = 9/10q + 1/4 ⟹7/5 x 2/3-1/4= 9/10q ⟹ Q = 41/54 ∴ p < q
