Answer 1

The correct option is B 61.8 g

Initially, Merry added 49.5 g of sugar.

Later, she added 12.3 g of sugar more.

Total amount of sugar that she added is
$=\text{Amount added initially}+\text{Amount added later}$
$=49.5\text{g}+12.3\text{g}$

We add decimal numbers by aligning the decimal point.
Total amount of sugar in the chocolate cake $=61.8\text{g}$
