Question

A man ate 100 grapes in 5 days. Each day he ate 6 more grapes than those he ate on the previous day.
How many grapes did he eat the first day?​

Answer 1

he ate 30 grapes in total

and he ate 31 grapes on first day

Answer 2

First day bananas = x

Eating 6 more than the previous day means x+6,x+12,x+18,x+24( for 5 days)

X+(x+6)+(x+12)+(x+18)+(x+24) = 100

5x = 100–60

X = 40/5

X = 8

Therefore,first day she ate 8 bananas
