Verified Answer: Kenny did 25 pushups. His older brother, Sal, did twice as many pushups as Kenny. Then, their oldest sister, Natalie, did 10 more pushups than Sal. How many pushups did the three children do altogether?
Solution: From the question, it is given that
Kenny did 25 pushups ────── ①
Sal did twice pushups as Kenny
∴Sal did 2×25 pushups = 50 ────── ②
After that
Natalie did 10 more pushups than Sal
∴ Natalie did 50+10 pushups = 60 ────── ③
Adding equations ①, ② and ③, we get
25 + 50 + 60
Hence, three children did 153 pushups altogether.
Conclusion
Kenny did 25 pushups. His older brother, Sal, did twice as many pushups as Kenny. Then, their oldest sister, Natalie, did 10 more pushups than Sal. Three children did 153 pushups altogether.
