Question

Aanya got 5 marks in science test. Her friend Sneha got ‘x’ marks more than Aanya. How many marks did they get together?
A) $5 \times x$
B) $5 + x$
C) $10 + x$
D) $2x + 5$

Answer 1

Hint:This problem is based on linear equations. When the equation has only one variable, then this type of equation is known as a linear equation in one variable.In this question determine the marks obtained by Aanya and Sneha individually and then add them to find the marks obtained by them altogether.

Complete step-by-step solution
According to the question,
Marks obtained by Aanya in science test = 5
As Sneha got ‘x’ marks more than Aanya,
∴Marks obtained by Sneha in science test = x+5
We have to find the marks obtained by them altogether so we will add the marks obtained by them individually in the science test.
Marks obtained by both of them = \[5 + x + 5\]
$ = 10 + x$
Hence, the marks they got altogether is 10+x
∴ Option (C) is correct.

Note: To solve these types of questions,first we will define the numbers in terms of the same variable and then move further calculation.Here we have to perform arithemtic operation on the same variable. Be sure to read the problem carefully to discover how all the numbers relate to each other.
