Question

There are z chocolates in a basket. Ram took out x chocolates from it. If Rasheeda comes and takes away another y chocolates from the same basket, then how many chocolates are left in the basket now?

• A. $z+(x-y)$
• B. $z-(x-y)$
• C. $z-(x+y)$
• D. $z+(x+y)$

Answer 1

The correct option is C

$z-(x+y)$

Number of chocolates that the basket initially had = $z$

Number of chocolates in the basket after Ram took out 'x' chocolates = $z-x$

Number of chocolates in the basket after Rasheeda takes away 'y' chocolates = $(z-x)-y$

We know that, instead of subtracting two numbers one after another, we need to only subtract the sum of these two numbers.

So, $(z-x)-y=z-(x+y)$

Therefore the number of chocolates left in the basket = $z-(x+y)$
