When equal volumes of two substance are mixed, the specific gravity of the mixurie is 4. When equal weights of the same substance are mixed, the specific gravity of the mixture is 3. The soecufuc gravities of the two substance could be

The average weight of a class of students is 67.5kg. The weight of the class teacher is 25% more than the average weight of the class.The averrage weight of the class is less than the class teacher by x%. The value of x is :

When equal volumes of two substances are mixed together, the specific gravity of the mixture is 5. But when equal weights of the same substance are mixed together, the specific gravity of the two is 3. Find the specific gravity of two substances.

The average weight of 30 students in a class is 25kgs. If the weight of the class teacher is added, the average weight increase by 2kgs. The weight of the class teacher (in kgs) is A. 86 B. 84 C. 81 D. 87

There are 50 students in a class in which boys are 8 more than the girls. Average weight of all the students is 50.5 kg and the average weight of all the girls is 48.5 kg then find the average weight of all the boys.
