V1/V2 = T1/T2

T2 = V2/V1 ×T1
      = 80/100×300k
           =240k

33 degree Celsius
Its not necessary to change unit of volume
As it is ratio of both in the formula
And as pressure is same in the question it will be cancelled out
And it is always necessary to take temperature in kelvin

Take eq. P1V1  =  P2V2
                T1          T2
here, P1=740mm  V1 = 100ml ⇒ 100/1000 liter ⇒ 0.1 L
         T1 = 27 c ⇒ 27 + 273 = 300 K
        P2 = 740 mm  V2 = 0.08 L  T2 = X
put value in eq.
     ⇒  740 × 0.1  = 740 × 0.08
               300              x
     ⇒  X = 740 ×0.08 ×300
                     740 × 0.1 
     ⇒ X = 240 K
T2 = 240 K

welcome
if ot helps u mark me best.. :)
pl can youtell it to me in celcius
it's -33.15 C > K = 273 - C
Thanks a lot
