# Four integers are rounded to the nearest 10 and the sum of the four rounded numbers is 90 so what is the maximum possible sum of the four original numbers?

a number can be rounded up if the ones digits is 5,6,7,8, or 9 . it can be rounded down if the ones digits is 4,3,2, or 1. the maximum number can be calculated the number rounded down and largest value can be 4. therefore, =3*4 =12 so 12 is more than 90 =12+90 =102 so sum of original value is 102
