hi, i have another 2 questions that need your help.


1. 608 children took part in a skipping competition. Altogether 110 Gold awards were presented to 1/5 of the boys and 1/7 of the grils. How many boys took part in the competition.

2. The ratio of Steven’s cards to Benny’s cards was 3:4. After Steven bought another 9 cards and Benny lost 18 cards, the ratio became 3:2. Find the total number of cards Steven and Benny had at first.

Thank you.

Hi

q2 is similar to the one you posted earlier - \"Atrirah & Malek\".

Initially, Steven's cards : Benny's cards = 3u : 4u
After Steven bought 9 cards --> Steven's cards = 3u + 9
Benny lost 18 cards --> Benny's cards = 4u - 18
3u+9 : 4u-18 = 3:2

Cross-multiply --> 6u + 18 = 12u - 54, 6u = 72, 1u = 12 .. I think you can carry on from here.

q1 can be solved using the \"stars & moons\" method the students learned in P1-P3.

Girls = * * * * * * * } 608
Boys = # # # # # }

* + # = 110,
so * * = 608 - 5 x 110 = 58,
* = 29
# = 110 - 29 = 81

Boys = 5 # = 405

cheers.

hi Guru, thank you for your clear explanation. Q1 seems to be a problem. I have a feeling that the information is insufficient for this question.

Hi, anyone can help me with this?


Ahmad has $40 more than Ben. After giving 1/5 of his money to Ben, Ben now has 7/8 of what Ahmad has. How much did they have?
