Question

on an average jane write 12 stories every year although in first year she was able to write some more stories if after 12 year f her career she written 147 stories how many had she written after 7 year of her writing​

Answer 1

Answer:

87 storiea

Step-by-step explanation:

Given: Average of 12 years = 12

=> Sum of stories in 12 years / 12 = 12

=> Sum of stories in 12 years = 12 × 12 = 144

Therefore,

Sum of stories in 6 years = 144/2 = 72

According to question,

Sum of stories in 12 years = 147

So number of extra stories written in first year = 147 - 144 = 3

So in first year, Jane wrote 12 + 3 = 15 stories

Therefore,

in 7 years Jane wrote the stories

= 15 + stories written in 6 years

= 15 + 72

= 87
