Answer:
Option D - December
Step-by-step explanation:
Given : Mandy read 16 books this year and read 2 books each month.
Bill wants to catch up to Mandy and follow:
Month Books
May- 4
June- 8
July- 12
From this table bill increases his books by 4 per month.
and Mandy Increases her books by 2 per month.
Let x represent the no. of months (x=1 represent the May)
Therefore,
For Mandy who already read 16 books in the end of April and reads 2 books each month ⇒ 16+2x
For Bill he wants to catch Mandy so he started with reading 4 books in a month ⇒4x
The month will Bill have read the same amount of books as Mandy
16+2x=4x
⇒16=2x
⇒x=8
i.e, from May to 8 months ⇒December
Month(x) Mandy(16+2x) Bill(4x)
May(1) 18 4
June(2) 20 8
July(3) 22 12
August(4) 24 16
September(5) 26 20
October(6) 28 24
November(7) 30 28
December(8) 32 32
At the end of December they will have read the same amount of books.
Hence, Option D is correct.
