Question
In a cricket team scores X runs on average over N games, and then scores Y runs in the next game, then the average score for the team over the (N+1) games is :
(X+Y)/(N+1)
(NX+Y)/(N+1)
{N(X+Y)} /(N+1)
{N(X+Y)-1}/N
{(N+1) (X+Y)} /(N+1)
ANSWER : 2
Descrption
<p style="margin-left:0px;">The average score for the team over (N+1) games can be calculated as follows:</p><p style="margin-left:0px;"><strong>Total Runs After N Games:</strong> The first N games is the average (X) multiplied by the number of games (N). So, total runs after N games = N * X.</p><p style="margin-left:0px;"><strong>Total Runs After (N+1) Games:</strong> After the next game, Y runs are added to the previous total. Therefore, total runs after (N+1) games = N * X + Y.</p><p style="margin-left:0px;"><strong>Average Score After (N+1) Games:</strong> we divide the total runs after (N+1) games by the number of games (N+1). So, average score = (N * X + Y) / (N + 1).</p><p style="margin-left:0px;">Therefore, the average score for the team over the (N+1) games is <strong>(N * X + Y) / (N + 1)</strong>.</p>
