Answer 1

Answer:

Answer 2

Step-by-step explanation:

Given that: In a test, Neha gets twice the marks as that of Parul. Two times Neha's marks and three times Parul's marks make 210.

To find:Find the marks obtained by Neha ?

Solution: Let us assume that Neha get x marks and parul get y marks in the same exam

ATQ,

Neha gets twice the marks as that of Parul

$\bold{x = 2y} \: \: \: ...eq1$

and,Two times Neha's marks and three

times Parul's marks make 210.

$\bold{2x + 3y = 210} \: \: \: \: ...eq2$

Substitute the value of x from eq1 into eq2

$2(2y) + 3y = 210 \\ \\ 4y + 3y = 210 \\ \\ 7y = 210 \\ \\ y = \frac{210}{7} \\ \\ \bold{y = 30}$

Put the value of y in eq1

$x = 2 \times 30 \\ \\ \bold{x = 60}$

Thus, Neha get 60 marks.

Option B is correct.

Hope it helps you.
