(b) $1620 - $180 = $1440
Total sales (S) = $1440/2 = $720
Total sales (M) = $720 + $180 = $900
1 S = $720/80 = $9
1 M (after 25% discount) = $900/100 = $9
1M (original cost) = 100/75 x $9 = $12
1 M - 1 S (original) = $12 - $9 = $3 (Ans)
Total sales (S) = $1440/2 = $720
Total sales (M) = $720 + $180 = $900
1 S = $720/80 = $9
1 M (after 25% discount) = $900/100 = $9
1M (original cost) = 100/75 x $9 = $12
1 M - 1 S (original) = $12 - $9 = $3 (Ans)

(a). Total number of T-shirts = 2 x 400
= 800
M + XL = 800 - 80 - 480 = 320
M : XL: total
5 : 11 : 16 (x20)
100 : 220 : 320
100 T-shirts are in size M (Ans)
= 800
M + XL = 800 - 80 - 480 = 320
M : XL: total
5 : 11 : 16 (x20)
100 : 220 : 320
100 T-shirts are in size M (Ans)
