Answer:
47
Step-by-step explanation:
There are total 52 cards.
Certain number of cards are lost.
When divided by 4, leaves 3 cards remain ; 51, 47, 43, 39, . . .
When divided by 5, leaves 2 cards remain : 47, 42, 37, 32, . . .
When divided by 3, leaves 2 cars remain : 50, 47, 44, 41, . . .
The common number among the three is 47.
29 miles
because town y is between town x and town z so you can take the distance between town x and town z and subtract the distance from town y to town z
3 buses x 42 = 126... So the final bus will carry 155-126=29 students.... Mental Math.
