Question

Rajesh is in-charge of buying bread rolls and buns for a party. There are $10$ buns in each box of buns and 8 bread in each box of bread rolls. Rajesh wants to buy exactly the same number of buns and bread rolls. What is the smallest number of boxes he should buy for buns alone?

• A. $10$
• B. $8$
• C. $4$
• D. $5$

Answer 1

The correct option is C $4$

Required number of breads and rolls = LCM of $(10,8)$
$10=2\times 5$
$8=2\times 2\times 2$
LCM $=40$
To keep $40$ bread and rolls, he needs $4$ boxes.
