Answer 1

Answer:

my answer came to be 0 so option 1

can anyone tell if it's right or wrong

Step-by-step explanation:

20% of 21853 marketing MBAs = (20/100)*21853 = a

salary of 20% marketing MBAs = (20/100)*2622= b

salary of one marketing MBA = salary of (a) marketing MBAs /total marketing MBAs = b/a

= [(20/100)*2622] / [(20/100)*21853]

2262/21853

Now similarly for strategy MBAs

salary of one strategy MBA = b'/a'

=[(16/100)*2622] / [(16/100)*21853]

= 2622/21853

so difference came out to be zero.

is it correct?
