Question

$950$ crank cases are manufactured every day in a factory. How many such cases will be manufactured altogether in the months of October, November, and December? (Assume that the factory works on all the days in these $3$ months.)

• A. $83700$
• B. $85400$
• C. $84700$
• D. $87400$

Answer 1

The correct option is D $87400$

No of crank cases manufactured everyday $=950$
No of crank cases manufactured in the month of October $=$ $31\times 950$ $=29450$
No of crank cases manufactured in the month of November $=$ $30\times 950$ $=28500$
No of crank cases manufactured in the month of December $=$ $31\times 950$ $=29450$
Total no of crank cases manufacture in all the $3$ months $=29450+28500+29450=87400$
