Question

A player who was playing video game was given 18 coins to begin with the game. To go to the next level, he needs to spend 4 coins and if he succeeds the particular level, he earns 6 coins. Find the number of coins he collects after clearing each level (assuming he clears every level).

• A. 18, 20, 22, 24, 26………
• B. 18, 23, 28, 33, 34………
• C. 18, 22, 26, 28, 32………
• D. 18, 24, 30, 36, 42………

Answer 1

The correct option is A 18, 20, 22, 24, 26………

Initial coins the player has is 18 coins

Net no. of coins he gain after clearing a level = coins gained - coins spent
= 6 - 4
= 2

$\therefore$ Coins he has after clearing first level = 18 + 2 = 20

No. of coins after clearing second level = 20 + 2 = 22

No. of coins after clearing third level = 22 + 2 = 24

So, the series of coins after clearing each level is 18, 20, 22, 24, 26………
