the average runs of a cricket player of 12 innings was 48 . how many runs must he make in his next innings so as to increase his average of runs by 10 ?
"explanation : average after 13 innings = 58 required number of runs = ( 58 * 13 ) – ( 48 * 12 ) = 754 – 576 = 178 answer d"
subtract(multiply(add(12, const_1), add(48, 10)), multiply(48, 12))
