The average weight of 25 students is 30 kgs. If one student excluded, the average remaining students weight becomes 29 kgs. What is the weight of excluded student?
Answers
Answer:
Correct option is
C
45 kg
Total weight of 24 students =24×35=840kg
Total weight of 25 persons with teacher =25×35.4=885kg.
∴ Weight of teacher =(885−840)kg=45kg
Answer:
The weight of excluded student is 54 kg.
Explanation:
From the question, we have
Total weight of 25 students =25 × 30 = 750 kg
Total weight of 24 students =24 × 29= 696kg.
∴ Weight of excluded student =(750-696)kg= 54 kg
The weight of excluded student is 54 kg.
Multiplication:
Mathematicians multiply the numbers to find the product of two or more numbers. We regularly carry out one of the basic mathematical procedures. The primary application that is obvious is using multiplication tables. In mathematics, the repeated addition of one number in relation to another is symbolised by the multiplication of two numbers. These numbers may be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, m is either added to itself 'n' times or the opposite is true. The method used to multiply integers and decimals is the same. The position of the decimal (.) must be taken into account after multiplication.
