  1. Correct Answer – B
    `M_(1)V_(1)+M_(2)V_(2)=M_(3)(V_(1)+V_(2))`
    `0.5xx750+2xx250=M_(3)(750+25)`
    `375+500=1000M_(3)`
    `therefore” “M_(3)=(875)/(1000)=0.875M.`

  1. Correct Answer – B
    `M_(1) V_(1) + M_(2) V_(2) = M_(3) (V_(1) + V_(2))`
    `0.5 xx 750 + 2 xx 250 = M_(3) (750 + 250)`
    or `375 + 500 = 1000 m_(3)`
    `M_(3) = 875/1000 = 0.875 M`
