Question

If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

Answer 1

Answer:

23 days

Step-by-step explanation:

Given,

No. of days taken by Jenny to read 7 books

= 8

So,

No. of days taken by her to read 1 book

$= \frac{8}{7}$

Therefore,

No. of days taken by her to read 20 books

$= \frac{8}{7} × 20$

• [On Simplification]

$= \frac{160}{7}$

• [On dividing]

= 22.85.....

• [On approximating]

= 23 days (approx. )

Hence,

Jenny will take 23 days to read 20 books (Ans)
