The correct option is B 20
Total number of cupcakes for sale = 24
Fraction of cupcakes sold on Day 1 =
24
∴ Number of cupcakes sold on Day 1
= 24×24
=24×24
=484
= 12
∴ Sid sold 12 cupcakes on Day 1.
Fraction of cupcakes sold on Day 2 =
13
∴ Number of cupcakes sold on Day 2
= 24×13
=24×13
=243
= 8
Sid sold 8 cupcakes on Day 2.
∴ Total number of cupcakes sold in all = 12 + 8 = 20
Hence, Sid sold 20 cupcakes in all.
