Correct Question :-

Q The mean weight of a class of 35 students is 45 kg.If the weight of the teacher be included,the mean weight increase by 500g.Find the weight of the teacher.

$\bf{\underline{Solution}}:-$

Mean weight of 35 students = 45 kg

Total weight of 35 students = 45 × 35 kg

Total weight of 35 students = 1575 kg

Now,

convert 500 g into kg,

• 500/1000 = 0.5 kg

Mean weight of 35 students including

teacher = 45 + 0.5 kg

Mean weight of 35 students including

teacher = 45.5 kg

Total weight of 35 students including

teacher = 45.5 × 36

Total weight of 35 students including

teacher = 1638 kg

Weight of the teacher = 1638 - 1575 kg

Weight of the teacher = 63 kg

Hence,the weight of the teacher will be 63 kg.
