Question

Mary baked $93$ cookies . She gave away $41$ cookies to Charlie. Mary has cookies left .

• A. $134$
• B. $25$
• C. $52$
• D. $62$

Answer 1

The correct option is C $52$

To find out how many cookies Mary has, we need to subtract $41$ from $93$

Aligning both the numbers according to Place value (starting from the right):

We place the like terms of the digits together i.e. digits at ones place will be placed together and digits at tens place to be placed together.

By subtracting $1$ ones from $3$ ones, we get $2$ ones.

Similarly, by subtracting $4$ tens from $9$ tens, we get $5$ tens.
Thus, Mary is left with $52$ cookies.
