Question

Nived had 40 marbles. In the first 6 games he lost 4 marbles each. And in the last 4 games he got 3 marbles each. How many marbles does he have now?

• A. 76
• B. 28
• C. 52
• D. 4

Answer 1

The correct option is B 28

The number of marbles Nived had = 40
The number of marbles he lost $=6\times (-4)=(-24)$
The number of marbles he gained $=4\times (+3)=12$
$\therefore$ The total number of marbles Nived has at the end $=40+(-24)+12$
$=28\text{marbles}$
