Question

Rahul bought $9$ kg $250$ g of fruits (mangoes and apples). He had $5$ kg $460$ g of mangoes. What is the weight of apples?

• A. $3$ kg $900$ g
• B. $3$ kg $790$ g
• C. $2$ kg $560$ g
• D. $3$ kg $250$ g

Answer 1

Answer: (B)

Total weight of Fruits (mangoes + apples ) is $9$ $kg$ $250$ $gm$

We know that $gram$ is abbreviated as $gm$

$1$ $kg=1000$ $gram$

(i) Weight of Mangoes is $5$ $kg$ $460$ $gm$

$5$ $kg$ $460$ $gm$ $=5kg+460gm$ $=A$ ........... $\left(1\right)$

$9$ $kg$ $250$ $gm$ $=8kg+1kg+250gm$ $=8kg+1250gm=B$ ............ $\left(2\right)$

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

$B-A=[8$ $kg$ $1250$ $gm$] $-$ [$5$ $kg$ $460$ $gm$]

$B-A=[8$ $kg$ $-$ $5$ $kg$] $+$ [$1250$ $gm$ $-$ $460$ $gm$]

$B-A=3kg$ $+$$790$ $gm$

Weight of apples is $3kg$ $790gm$

Hence, Option $B$ is correct
