Question

P +1/q =4 q +1/r =1 r 1/p =7/3 pqr=?

Answer 1

Answer:

pqr = -1

Step-by-step explanation:

p + 1/q = 1

∴ pq + 1 = q ..…… (1)

q + 1/r = 1

∴ qr + 1 = r ………(2)

MULTIPLYING BOTH SIDES BY r IN (1)

pqr + r = qr

qr from (2) is r - 1

So, pqr+ r = r - 1

pqr = -1

Answer 2

Answer:

Step-by-step explanation: hit and trial

P, q,r = 3/2 , 2/5, 5/3

Pqr= 1
