PSLEThere are some stickers in albums K and L. 75% of the stickers in album K and 25% of the stickers in album L are square stickers. There is an equal number of round stickers in both albums. If there are 64 more square stickers in album K than in album L, 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 square stickers in Album K than Album L
= 9 u - 1 u
= 8 u
8 u = 64
1 u = 64 ÷ 8 = 8
Number of stickers in both albums
= 9 u + 3 u + 1 u + 3 u
= 16 u
= 16 x 8
= 128
Answer(s): 128
