Question

Shilpa Pack 30 T-shirts at a clothing store. Of the T-shirts Shilpa bought, 20% Were blue and 50% were black but how many of the T-shirts were neither black nor blue

Answer 1

9

Explanation:

Given that :

Total number of Tshirts = 30

% of blue T shirts = 20%

% of black T shirts = 50%

Number of Blue = 0.2 * 30 = 6

Number of black = 0.5 * 30 = 15

Number of Tshirts that are neither black nor blue :

Total - ( number of blue + number of black)

30 - (15 + 6)

30 - 21 = 9

9 Tshirts
