Question

I have few pens to be distributed. If I keep $4,5$ or $6$ in a pack, I am left with three pens. If I keep $7$ in a pack, I am left with none. What is the minimum number of pens, I have to pack and distribute?

• A. $56$
• B. $61$
• C. $62$
• D. $63$

Answer 1

Answer: (D)

$63$

$(LCMof4,5,6)+3=60+3=63$
When $63÷7$, No remainder is left.
Hence, option 'D' is correct.
