Question

in an examination ravi scored 70 marks ,but he scored 6 marks less than double the marks scored by his friend anil.what is the mark scored by anil?​

Answer 1

Answer:76 marks

Step-by-step explanation:

Ravi's score -70

Anil's score-2x

2x-6=70

2x=70+6=76

X=76/2=38

Therefore, Anil's score is

2 X 38

=76

Answer 2

${\huge {\boxed{\bold{\boxed{\mathfrak{\color{red}{Answer}}}}}}}$

Assume that x be the marks obtained by Ravi in the third unit test.

It is given that the student should have an average of at least 60 marks.

From the given information, we can write the linear inequality as:

(70+75+x)/3 ≥ 60

Now, simplify the expression:

⇒ (145 +x) ≥ 180

⇒ x ≥ 180 -145

⇒ x ≥ 35

Hence, the student should obtain a minimum of 35 marks to have a average of at least 60 marks
