Question

Akshay ate 72 bananas in six days, each day eating 4 more than the previous day.
How many bananas did he eat on the third day?

Answer 1

10 bananas

---

Let x be the amount of bananas eaten on the first day, then we have:
Day 1---- x
Day 2---- x+4*1
...
Day 6 ---- x+4*5
Total ---- x*6 +4*(1+2+3+4+5)=72 ==>
==> 6x+60=72---> x=2
Day 3 would be 2+4*2=10 bananas
