2 resistors in series formula is = R1+R2
so 1.2+1.2 = 2.4k ohm
now it parellel wid 3.3k ohm
parallel formula is R1*R2/R1+R2
so 2.4+3.3/2.4+3.3=1.389k ohms
killo ohms into ohms by multipication 1000
=1.38947*1000
=1389.47 ohms
=1389 ohms

Nice explaination Deepika & Madhu metha

Two resistors of value 2.4k ohms

i.e 1.2+1.2=2.4k ohms

Therefore R1=2.4k ohms. This R1 is connected parallel with 3.3k ohms.
we asume 3.3k ohms=R2

The parallel formula is=(R1*R2)/(R1+R2)
=2.4*3.3/(2.4+3.3)
=7.92/5.7
=1.38947k ohms

To convert the killo ohms into ohms by multipication 1000

Therefore;

=1.38947*1000
=1389.47 ohms

Two resistors of value 1.2k ohm each in series can be added up. connected in parallel with 3.3.k ohm.

((2.4*3.3)/(2.4+3.3))*1000 = 1389.47 for k
