Option B is correct 1/10 & 3/20 are values of Q & R
Step-by-step explanation:
Let say PQ = QR = RS = N
then PQ + QR + RS = 1/5 - 1/20
=> N + N + N = (4 - 1)/20
=> 3N = 3/20
=> N = 1/20
Vale of Q = 1/20 + 1/20 = 2/20 = 1/10
Value of R = 1/5 = 1/20 = (4 - 1)/20 = 3/20
Option B is correct 1/10 & 3/20 are values of Q & R
