The average of runs of a cricket player of 20 innings was 36. How many runs must he make in his next innings so as to increase his average of runs by 4 ?
Select the correct option:
A) 96	B) 106	C) 122	D) 116	E) 120
Average = total runs / no.of innings = 36   So, total = Average x no.of innings = 36 * 20= 
<gadget id="calculator">36 * 20</gadget>
<output>720</output>
720   Now increase in avg= 4 runs. So, new avg = 36+4= 
<gadget id="calculator">36+4</gadget>
<output>40</output>
40 runs   Total runs= new avg x new no. of innings = 40 * 21= 
<gadget id="calculator">40 * 21</gadget>
<output>840</output>
840   Runs made in the 11th inning= 840-720= 
<gadget id="calculator">840-720</gadget>
<output>120</output>
