the average runs of a cricket player of 5 innings was 20 . how many runs must he make in his next innings so as to increase his average of runs by 3 ?
"explanation : average after 6 innings = 23 required number of runs = ( 24 * 6 ) – ( 20 * 5 ) = 144 – 100 = 44 answer c"
subtract(multiply(add(5, const_1), add(20, 3)), multiply(20, 5))
