the average age of 15 students of a class is 15 years. out of these, the average age of 5 students is 14 years and that of the other 9 students is 16 years. tee age of the 15 th student is?
subtract(multiply(15, 15), add(multiply(5, 14), multiply(9, 16)))
"age of the 15 th student = [ 15 * 15 - ( 14 * 5 + 16 * 9 ) ] = ( 225 - 214 ) = 11 years . answer : a"
