The number of T-shirt bought by Shilpa from a clothing store = 30
Percentage of T-shirt that were blue = 20%
Then Number of T-shirt that were blue in color = (20/100) * 30
= 2 * 3
= 6
Number of T-shirts that were black in color = (1/2) * 30
= 15
Then
The total number of T-shirts that were black and blue = (15 + 6)
= 21
Then
The total number of T-shirts that were neither black nor blue = 30 - 21
= 9
So the number of T-shirts that were neither black nor blue was 9.
90 is the LCM of 30 and 45
51/3 is equal to 17 hope it helps
