 <translate> Total age of students is 32X16 = 512 Years
Total age inclusive of teacher = 33X (16+1) = 561
So, Teacher's age is 561-512 = 49 Yrs
There is a shortcut for these type of problems
Teacher's age is 16+(33X1) = 49 Years So the answer is (A). <yor> Apapọ ọjọ ori awọn ọmọ ile-iwe jẹ 32X16 = 512 Ọdun Apapọ ọjọ ori pẹlu ti olukọ = 33X (16+1) = 561 Nítorí náà, ọjọ́ orí Olùkọ́ ni 561-512 = 49 Yrs Ọ̀nà àbáyọ wà fún irú àwọn ìṣòro yìí Ọjọ́ orí olùkọ́ jẹ́ 16+(33X1) = 49 Ọdún Nítorí náà ìdáhùn náà ni (A).
