Hi bobsg01,

this is similar to a question that was discussed before - http://www.flickr.com/photos/62167097@N02/5661546018/in/photostream

When 8 sweets given to each girl, left over 25 sweets.
When 11 sweets are given to each girl, last girl had only 6 - ie short of 5.

25 + 5 = 30
11-8 = 3
30 / 3 = 10, so there were 10 girls.
Number of sweets = 8 x 10 + 25 = 105.

cheers.

Hi,


Can someone help to solve these two questions. TIA

1) Mrs Gopal and Mrs Ari went to the supermarket.
Both women decided to spend all their money on either apples or pears and they would not buy the same fruit.
If Mrs Gopal bought only pears, she would have 9 more fruit than Mrs Ari.
If she bought only apples, she would have 41 more fruit than Mrs Ari.
How much more money has Mrs Gopal than Mrs Ari?
Ans: $12

2) Talik was given some pocket money for recess. He realised that if he had spent $0.80 on each meal, he would have 8 meals fewer than if he had spent $0.60 per meal.
Talik spent $0.60 on 8 meals and spent $0.80 on the remaining meals. How many meals did the money last him?
Ans: $26
