PSLEThere are some stickers in albums U and V. 75% of the stickers in album U and 25% of the stickers in album V are oval stickers. There is an equal number of round stickers in both albums. If there are 176 more oval stickers in album U than in album V, how many stickers are there in both albums altogether?

34The number of round stickers in both albums is the same. Make the number of round stickers the same. LCM of 1 and 3 is 3.
Number of more oval stickers in Album U than Album V
= 9 u - 1 u
= 8 u
8 u = 176
1 u = 176 ÷ 8 = 22
Number of stickers in both albums
= 9 u + 3 u + 1 u + 3 u
= 16 u
= 16 x 22
= 352
Answer(s): 352
