is answer 300.029997nsec?? else u can go with 300.03nsec.
Yeah it is 300.03 .But can u pls provide a step wise solution . Im not getting how to simplify it :(

 @dulqar, 1/109 = 1 nsec = 1*10-9 sec.

so first term will become 30* 10-3  * 10-9 (because of 1/109)= .03nsec

in second term 300* 10-9 is given so u can take it as 300nsec

so it will become 300nsec*(1 - (1/109)) == 300nsec*(1 - 10*9)

so the -ve term is quite small so we can neglect this term so addtion of 1st and 2ns term is 300nsec + .03nsec
