Question

$(123+5.6)-3.6$ equals

• A. 121
• B. 125
• C. 113.8
• D. 132.2

Answer 1

The correct option is B

125

We know that $(x+y)-z=x+(y-z)$, for all numbers $x$, $y$, $z$ with $y>z$.

Since the above is true for all the numbers, it must be true for $x=123$, $y=5.6$ and $z=3.6$ also, as $y=5.6>3.6=z$

So, $(123+5.6)-3.6$ = $123+(5.6-3.6)$ = $123+2$ = $125$
