Question

Subtract $2\text{kg}54\text{g}$ from $12\text{kg}530\text{g}$.

• A. $10\text{kg}476\text{g}$
• B. $104\text{kg}76\text{g}$
• C. $1\text{kg}476\text{g}$
• D. $1047\text{kg}6\text{g}$

Answer 1

Answer: (A)

We know $1$ kg $=1000$ gm

(i) We have to subtract $2$ kg $54$ gm from $12$ kg $530$ gm

$2$ kg $54$ gm $=2$ kg $+$ $54$ gm $=A$ .......(1)

$12$ kg $530$ gm $=12$ kg $+$ $530$ gm $=B$ .......(2)

Now as per the question, we have to subtract $A$ from $B$

$B-A=[12$ $\text{kg}$ $530$ $\text{gm}$] $-$[$2$ $\text{kg}$ $54$ $\text{gm}$ $]$

Subtract like terms

$B-A=[12\text{kg}-2\text{kg}]+[530\text{gm}-54\text{gm}]$

$B-A=10$ kg $+$ $476$ gm

So, option A is correct
