1) Irene, Doreen, Shawnia and Ruth made some balloons. Doreen made 252 balloons at first. Ruth donated some of her balloons and her number of balloons decreased by 20%. Irene made another 40% of her balloons. Shawnia gave away 30 fewer balloons than what Doreen had made. In the end, they had an equal number of balloons. How many balloons did they make altogether at first?

2) In a bakery shop, there are some curry, sardine and kaya buns. There are 216 more curry than sardine buns. There is 3 times as many curry as kaya buns. There is 12% as many sardine buns as the total number of buns. How many buns are there in the bakery shop?

Since 20% was given from H to L, let L be 5u

L: 5u

H: 5u + 45

H gave 20% to L.

20% of 5u = 1u

20% of 45 = 9

L: 6u + 9

H: 4u + 36

L gave 2/3 to H.

2/3 of 6u = 4u

2/3 of 9 = 6

L: 2u + 3

H: 8u + 42

H has 69 more than L.

69 = 6u + 39

6u = 30

1u = 5

1u + 9 = 5+9 = 14.

H gave 14 to L in the first place.
