Question

Machine $A$ can produce $7500$ biscuits in a day, which is $240$ fewer biscuits than what machine $B$ can produce in a day. Now, $20$ biscuits are placed in a pack. If both machines $A$ and $B$ are used, how many packs of biscuits will be there after 7 days?

• A. $5434$
• B. $2335$
• C. $4534$
• D. $5334$

Answer 1

The correct option is D $5334$

Number of biscuits machine $A$ produce in 1 day $=7500$
$\therefore$ Number of biscuits machine $B$ produced in 1 day $=7500+240=7740$
So, total number of biscuits produced in 1 day by both machines $A$ and $B$
$=7500+7740=15240$
$\therefore$ Number of biscuits produced in 7 days
$=15240\times 7=106680$
Now, number of biscuits in 1 pack$=20$
So, number of packs of biscuits
$=106680÷20=5334$
