Question

If a tiffin contains 4 sandwiches, how many sandwiches are there in 8 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 32 sandwiches.
