If p = (- 11 6 ), q = ( 21 4 ) and r = ( 283 6 ) , then which of the following is/are correct? 1. The value of p r is 2 . 2. p, q and r are in G.P. Select the correct answer using the code given below :

Step-by-step solution

aligned & p = (- 11 6 ) & p =- (2 - 6 ) & p = 6 = 1 3 & q = ( 21 4 ) &= (6 - 3 4 ) & q =- 3 4 =+ 4 =1 & r = ( 283 6 ) &= (46 + 7 6 )= ( + 6 ) & r = 6 = 3 & p r = 1 3 3 =1 aligned Statement (1) is incorrect. also p q = q r = 1 3 Sop, q, r are in G.P. Statement (2) is correct.
