Question

A tiffin contains $4$ sandwiches . How many sandwiches would be there in $8$ such tiffins?

• A. $24$
• B. $32$
• C. $40$
• D. $16$

Answer 1

The correct option is B $32$

We can see this as 8 groups of 4.

But, we know that 8 groups of 4 is the same as 4 groups of 8.

$4\times 8=8+8+8+8=32$

Thus, we have a total of $8\times 4=32$ sandwiches .
