Jordan was trading baseball cards with some friends. He gave 15 cards to Tommy and got 3 back. He gave two thirds of his remaining cards to Elaine and kept he rest for himself m. In the end he had 25 cards. How many baseball cards did he start with?

Answers

Answer 1

Answer:

87; If he gave two thirds of his remaining cards to Elaine, then he had one third left. If one third of his remaining cards is 25, then 25 x 3 will give you what he had after trading with Tommy. When he finished trading with Tommy he had 75 cards. if he gave away 15 cards, but got three back, then he must have had 87 cards to begin with.

Check your answer:

87-15 = 72

72+3 = 75

2/3 of 75 = 50

75-50 = 25

Great!

How many palimdromic numbers is there between 300 and 400

Answers

A palindrome is something that reads the same forwards and backwards.

If the number is a palindrome and it's between 300 and 400, then the
last digit must also be a ' 3 '.

So all we have left to fill in is the digit in the middle.

There are 10 possibilities for that one ... the digits ' 0 ' through ' 9 '.

So there are 10 palindromic numbers between 300 and 400.

Palindromic is where if you flip the number around (123 would become 321) then it is the same so:
303
313
323
343
353
363
373
383
393
so there are 10
