if the mean of numbers 28 , x , 50 , 78 and 104 is 62 , what is the mean of 48 , 62 , 98 , 124 and x ?
"mean = ( sum of all no . in series ) / ( no . in series ) m 1 = 62 = ( x + 28 + 50 + 78 + 104 ) / ( 5 ) 62 x 5 = 260 + x x = 50 therefore mean of 2 nd series m 2 = ( x + 48 + 62 + 98 + 124 ) / 5 m 2 = 76.5 answer = a"
divide(add(add(add(add(subtract(multiply(62, add(const_4, const_1)), add(add(add(28, 50), 78), 104)), 48), 62), 98), 124), add(const_4, const_1))
