  1. Correct Answer – 7
    `:. PV^(gamma)=`const.
    `P_(1)xx[(105V)/100]^(gamma)`=const.
    `:. (P_(1))/Pxx[105/100]^(gamma)`
    or `(P_(1))/P=[100/105]^(gamma)`
    or `(P_(1))/P=[100/105]^(7//5)`
    `:. P_(1)=0.93 P :. 7%` decrease in `P`

  1. Correct Answer – D
    `PV^(gamma)=` constant
    `P_(1)xx[(105 V)/100]^(gamma)=` constant
    `:.(P_(1))/Pxx[105/100]^(gamma)=1`
    or `(P_(1))/P=[100/105]^(gamma)`
    or `(P_(1))/P=[100/105]^(7//5)`
    `:. P_(1)=0.93 P`
    `:. 7%` decrease in `P`.
