Question

In a game, Mahesh has to earn coins. If he gets a gold coin, he gains 10 points, but if by mistake he gets a red coin, he loses 2 points. What is his total score if he gets 17 gold coins and 6 red coins?

Answer 1

$\text{Points gained for each gold coin =}10$

$\text{So, points gained for 17 gold coins}=10\times 17$
$\left[0.5mark\right]$

$\text{Similarly, for each red coin, points lost}=2$
$\text{Implies, points gained for each red}\text{coin =}-2$
$\left[0.5mark\right]$

$\text{Points gained for 6 red coins}=(-2)\times 6$
$\left[0.5mark\right]$

$\text{So, Mahesh's score:}=(17\times 10)+\left(\right(-2)\times 6)$
$\left[0.5mark\right]$
$=170+\left(\right(-2)\times 6)$
$=170+(-12)=170-12$
$=158$
$\left[1mark\right]$
