Question

Fill the given blank boxes.

• A. 22 and 35
• B. 21 and 34
• C. 21 and 35
• D. 22 and 34

Answer 1

The correct option is C 21 and 35

We can find the value of blank boxes by two ways
(i) Take the table of 2 and 5
(ii) Take the table of 3 and 4

Using the table of 2 and 5, we get
The number in blank boxes $2\times 3+5\times 3=6+15=21$
and $2\times 5+5\times 5=10+25=35$
The same can be done using the tables of 3 and 4.
