PSLEThere are some stickers in albums P and Q. 75% of the stickers in album P and 10% of the stickers in album Q are square stickers. There is an equal number of oval stickers in both albums. If there are 364 more square stickers in album P than in album Q, how many stickers are there in both albums altogether?

34The number of oval stickers in both albums is the same. Make the number of oval stickers the same. LCM of 1 and 9 is 9.
Number of more square stickers in Album P than Album Q
= 27 u - 1 u
= 26 u
26 u = 364
1 u = 364 ÷ 26 = 14
Number of stickers in both albums
= 27 u + 9 u + 1 u + 9 u
= 46 u
= 46 x 14
= 644
Answer(s): 644
