Question

Rogelio has completed a total of 168 pull-ups in gym class this year. The number of pull-ups Rogelio has completed is 30% of the number of the pull-ups Armando has completed. What is the minimum number of additional pull-ups Rogelio must complete in order for his number of pull-ups to be greater than Armando's if Armando does not complete another pull-up all year?

Answer 1

561

56 x 10 = 560 (100 percent of armandos pull ups)
