딸아이가 수학 문제를 물어봅니다... ^^
"아빠… 이 문제 잘 모르겠어요."
"그래… 어떤 문젠데..."
흠… 옛날 생각도 나고, 살짝 긴장도 되는군요... ^^
There is a group of boys and girls waiting for school buses.
25 girls get on the first bus.
The ratio of boys to girls at the stop is now 3 : 2.
15 boys get on the second bus.
There are now the same number of boys and girls at the bus stop.
How many students altogether were originally at the bus stop... ??
.
.
.
.
.
.
.
X : Y - 25 = 3 : 2
X - 15 = Y - 25
2X - 3Y = -75
X - Y = -10
X = 45
Y = 55
X + Y = 100
.

휴... 다행입니다... ^^
@abdullar nim, 산코피 na...
Math doesn't like me hahaha

I counted manually.
Boys : Girls
3 : 2
0 : 25 (bus 1)
45 : 30
15 : 0 (bus 2)
So,
30 : 30 (after bus 2)
Boys: 30+15 = 45
Girls: 30+25 = 55
Total: 100
No formula I used. Just manually. Great enigma!

순간..어렵네요. 저 공식대로는 못 풀겠어요. 아이들이 커 갈수록 저도 공부해야 할 것 같아요. 아이들에게 엄마가 수포자, 영포자였다는 사실을 들키면 안 되니까요~^^

Cool, uncluttered picture with one main subject and no distracting background details!
It reminds me of a tongue-twister I use on my Korean students: "Red Lorry, Yellow Lorry"...!
