Answer 1

Let the amount of oil in mixture be 4x and amount of water be 5x

then total quantity of first mixture=9x

similarly,

total quantity of second mixture=11x

it contains,5x oil and 6x water

total quantity of third mixture=13x

it contains 6x oil and 7x water

now let y be the equal quantity which is mixed from all.the three mixtures

then,

total amount of oil in it=4xy/9x +5xy/11x +6xy/13x

=4y/9 +5y/11 +6y/13

={(11×13×4y)+(5y×9×13)+(9×11×6y)}/1287

=1751y/1287

total amount of water in mixture=5xy/9x +6xy/11x +7xy/13x=5y/9 +6y/11 +7y/13

={(5y×11×13)+(6y×9×13)+(7y×11×9)}/1287

=2110y/1287

their ratio=1751y/1287:2110y/1287

=1751:2110

hence option c) is the correct one
