The tens digit of a two-digit number is two more than its unit digit. The two-digit number is 7 times the sum of the digits. Find the units digits? | [
"8",
"2",

Which of the following best approximates the value of the expression above?
Yes, answer 10^185 is correct. Note that we need approximate value of the given expression and as 10^(185) is much larger number than 10^(30) then 10^(30) is pretty much negligible in this case: 10^(185)-10^(30)=~10^(185).

If john makes a contribution to a charity fund at school, the average contribution size will increase by 50% reaching $75 per person. If there were 2 other contributions made before john's, what is the size of his donation? | [
"$250",
"$450",
"$150",
"$125"
] | D | Cavg = average contribution before John
Cavg*1.5 = 75, therefore the average cont is $50 before John.
If he needs to increase the average contribution by $25, he must put in $25 for each of the 2 people.
so $50.
But, he also has to put in the average for himself (the threeth person), so add $75.
So $125 is your answer.... | AquaRat_train |

Since Train B travels 50 miles / hour ; train A travels twice the speed of B which gives s1 = 100 miles/ hour
Time taken for train B = d2/s2 = 100 / 50 = 2 Hours
