tianzhu:yeah i also feel that there is some missing infoHiHiroii-kun:Hi this is a p4 qn.

Mrs Lim bought 12 pears and 4 apples. Mrs Tan bought 12 apples and 4 pears.
Mrs Tan paid $1.60 less than Mrs Lim. How much did a pear cost ?
From your question, we can tell that a pear costs 20 cents more than an apple.
Some information is missing, perhaps the cost of an apple?
Best wishes.

Dear gurus, please help with this qn.
There are 2 bags of stones labeled A & B. In bag A, there are 350 black stones and 500 white stones. In bag B, there are 400 black stones and 100 white stones. How many black and white stones should be transferred from bag B to bag A so that 50% of stones in bag A and 75% of stones in bag B are black?
Dharma:ooh thanks!4u + 5p = 10400 ........ (1)Hiroii-kun:Dear Gurus,
need help with this question.
At first, warehouse X and Y had a total of 10400 sacks of rice. After warehouse X has cleared 3/4 of its stock and warehouse Y has cleared 3/5 of its stock, warehouse Y now has 520 more sacks of rice than warehouse X. How many sacks of rice did each warehouse have at first?
Ans is 5600 & 4800 but cant seem to get it.
2p - 1u = 520 ..............(2)
8p - 4u = 2080 .............(2) x 4 = (3)
13p = 12480 ........(1) + (3)
1p = 960
1u = 1400
X => 4u = 4 x 1400 = 5600
Y => 5p = 5 x 960 = 4800
