Question

Find x and y

• A. $x=0,y=0$
• B. $x=0,y=1$
• C. $x=1,y=0$
• D. None of these

Answer 1

The correct option is C $x=1,y=0$

To find x and y let's perform the multiplication i.e. $1.25\times 12$
Step 1: Count the number of digits after decimal in 1.25 i.e. 2
Step 2: Ignore a decimal point and perform the multiplication, as you would with whole numbers as follows

Step 3: Now place a decimal point back.
1.25 has 2 decimal places. So, move the decimal point 2 places to the left in the product.
On comparison, $x=1,y=0$
