The answer would be D... both the statements are Sufficient... we know the base figure in the first statement... in the second one the percentage quantity is provided

(1) Friday night's attendance was 200.

(2) Attendance increased from Friday night to Saturday night by 16 people.



(1) friday =200
saturday = 200(1+8%) = 200(108/100) = 216
sufficient

(2) let friday = x people then
saturday =x (1+8%)

also given in (2)
x (1+8%) =x+16
108x= 100x + 1600
8x=1600
x=200=no. of people on friday
same as (1)
thus saturday = 216
sufficient

Ans D

Answer is D
Each statement itself is enough to solve the question.

1) friday night=200
inc of 8% on saturday night
so saturday night= (1.08)200

2) the difference between no. of people on friday and saturday is 16
since the number inc. by 8% on saturday
8% ( friday ) = 16
we get friday number
saturday number= friday + 16.

Hence D
