Answer

Explanation:

Step1: Calcular el número de estudiantes de 9º grado zurdos

El total de estudiantes de 9º grado es 121. El número de estudiantes de 9º grado diestros es 214 - 103 = 111. Entonces, el número de estudiantes de 9º grado zurdos es 121 - 111 = 10.

Step2: Calcular el número de estudiantes de 10º grado

El total de estudiantes es 236 y 121 son de 9º grado, entonces el número de estudiantes de 10º grado es 236 - 121 = 115.

Step3: Calcular el número de estudiantes de 10º grado zurdos

El total de estudiantes diestros es 214 y 103 son de 10º grado diestros, entonces el número de estudiantes de 10º grado zurdos es 115 - 103 = 12.

Step4: Calcular el total de estudiantes zurdos

El total de estudiantes zurdos es 10 + 12 = 22.
