Answer 1

Your Answer:-

The Right OPTION is (c). 5160$.

Solution :-

The Mean of Both is $2801.96 .

Let the sum of their salary be x.

So,

2801.96 = x/17+7

2801.96= x/24

x => 67247.04$

:::-

The Mean of Teaching assistants is 1831$.

Let the sum of their salary be y.

1831 = y/17

y=> 31127.

:::-

Difference of above one ,

=> 67247.04-31127

=> 36120.04 = Sum of Professors salary .

Mean => 36120.04/7

=> 5160.00571.

Rounding OFF ,

=> 5160 $ .
