Jaslyn had some orange and mangosteen face masks.
16 of them were orange. She gave away
13 of the orange face masks and
13 of the mangosteen face masks. In the end, she had 48 orange and mangosteen face masks altogether. How many mangosteen face masks did Jaslyn have at first?

Comparing orange and mangosteen face masks
at first |
1x3 =
3 u |
5x3 =
15 u |
6x3 =
18 u |
Before |
3 u |
3x5 =
15 u |

Change |
- 1 u |
- 1x5 =
- 5 u |
|
After |
2 u |
2x5 =
10 u |

The number of mangosteen face masks at first is repeated. Make the number of mangosteen face masks the same. LCM of 5 and 3 is 15.
Total number of face masks in the end
= 2 u + 10 u
= 12 u
12 u = 48
1 u = 48 ÷ 12 = 4
Number of mangosteen masks at first
= 15 u
= 15 x 4
= 60
Answer(s): 60
