Change the following statements using expressions into statements in ordinary language.
(For example, given Salim scores r runs in a cricket match, Nalin scores (r+15) runs. In ordinary language – Nalin scores 15 runs more than Salim.)
(a) A notebook costs Rsp. A book costs Rs 3p.
(b) Tony puts q marbles on the table. He has 8q marbles in his box.
(c) Our class has n students. The school has 20n students.
(d) Jaggu is z years old. His uncle is 4z years old and his aunt is (4z-3) years old.
(e) In an arrangement of dots there are r rows. Each row contains 5 dots.
(a) Here,
In the given question,
We know that,
Cost of a notebook = Rs p
And,
Cost of book = Rs 3p
Hence,
We can clearly observe that,
A book costs three times the cost of a notebook.
(b) Here,
In the given question,
We know that,
Number of marbles Tony puts on the table = q
And,
Number of marbles Tony has in his box = 8q
Hence,
We can clearly observe that,
Tony’s box contains 8times the number of marbles on the table.
(c) Here,
In the given question,
We know that,
Number of students in our class = n
And,
Total number of students in the school = 20n
Hence,
We can clearly observe that,
Total number of students in the school is 20 times the student of our class.
(d) Here,
In the given question,
We know that,
Age of Jaggu = z years
And,
Age of his uncle = 4z
And,
Age of his aunt = 4z - 3
Hence,
We can clearly observe that,
Jaggu’s uncle is 4 times older than Jaggu
And,
Jaggu’s aunt is 3 years younger than is uncle.
(e) Here,
In the given question,
We know that,
Number of rows = r
And,
Number of dots in each row = 5
Hence,
We can clearly observe that,
The total number of dots is 5 times the number of rows.
