My Solution:
2x10-6 = p(.4*5x10-3 + .6*15x10-3)  + (1-p)*1x10-6  , Hence p=0.00% (upto 2 decimal point)

2 * 10^-6 = (1-p) * 10^-6 + p *( 0.60*15000*10^-6 + .40*5000*10^-6 )

cancel common term i.e 10^-6 from the above equation.

2 = (1 - p) + p * (0.60*15000 + .40 *5000)

2 = (1 - p) + p*11000

2 = 1 - p + 11000p

1 = 10999p

p = 1/10999 = 9.091 * 10^-5

They have asked page fault rate in %

so , (9.091 * 10^-5) * 100 = 0.009091 approximately equal to 0.01

Hence 0.01 is correct answer.
