A) I don't know
B) 80
C) 21
D) 40
E) None of the above.
F) 16

Answer 1

hii mate your answer is

options no f that is 16

Answer 2

so 8 tee shirts can be worn in 8 ways 8C1=8!/7!(1!)=8 ways

similarly for 2 belts= 2C1=2!/1!(1!)=2 ways

for five pair of jeans= 5C1=5!/(4!)1!= 5 ways

so total number of ways=5*2*8=80 ways

so option B is correct

hope this helps
