We can set up a system of equations where is the sets of twins, is the sets of triplets, and is the sets of quadruplets. Solving for and in the second and third equations and substituting into the first equation yields. Since we are trying to find the number of babies and NOT the number of sets of quadruplets, the solution is not ...What is the tens digit in the sum. Solution. Since 10! is divisible by 100, any factorial greater than 10! is also divisible by 100. The last two digits of the sum of all factorials greater than 10! are 00, so the last two digits of 10!+11!+...+2006! are 00. So all that is needed is the tens digit of the sum 7!+8!+9!
