P1 = n1.R.T1/V1

P1 = n2.R.T1 + 50/V1 

n1.T1 = n2.T1 + 50

T1. n1/n2 - 1= 50 

n1/n2 = m1/m2 

T1.m1/m2 - 1= 50 

T1.4.0 g / 3. 2 g - 1= 50 

T1.1.25 - 1.00= 50 

T1 = 50/ 0.25= 200 K 

T = T1 = 200 K

but how can you take temp in k

As if we are in competition so we have to see just options which are being fit for the answer so we take 200 k only as no other option is fit for answer or may this question has some problem . So this is the only solution.

In above solution it is by mistake ( 40/3.2) Instead it is( 4/3.2).
