if the mean of numbers 38 , x , 70 , 88 and 110 is 69 , what is the mean of 50 , 72 , 97 , 125,147 and x ?
"mean = ( sum of all no . in series ) / ( no . in series ) m 1 = 69 = ( x + 38 + 70 + 88 + 110 ) / ( 5 ) 69 x 5 = 290 + x x = 39 therefore mean of 2 nd series m 2 = ( x + 50 + 62 + 97 + 125 + 147 ) / 6 m 2 = 86.67 answer = c"
divide(add(add(add(add(subtract(multiply(69, add(const_4, const_1)), add(add(add(38, 70), 88), 110)), 50), 72), 97), 125,147), add(const_4, const_1))
