accidents, acld attacks, rlots etc.
Two friends Rima and Sima together contributed Rs. 200 towards Prime
Minister Relief fund. Answer the following questions;
(a)Which one of the following is not a linear equation in two variables ?
(1) 2x + y = 3 (II) x + x = 1 (1H) 4 = 5x-4y (lv) * -- V2y = 3
(b) How to represent the above situation in linear equation in two
variables?
(1) 2x +y=200
(11) 200x=y
(III) x+y=200
(lv) 200=x - y
(c)lf Rima contributed Rs.76, then how much was contributed by Sima?
(1) Rs 120
(11) Rs 124
(III) Rs123
(iv) Rs 125
(d) If both contributed equally, then how much is contributed by each?
(it) Rs 50, Rs 50
(ili) Rs 100, Rs 100
(1) Rs 50, Rs 150
(iv)Rs 120, Rs 120

(c) Which is the standard form of linear equations in two variables
X.5?
(1) 5 0
(W) 1.X-50
(1) 1.x +0.7-5= 0​

Answer 1

Answer:

bellow:-

Step-by-step explanation:

Which out of the following is not the linear equation in two variables ?

x – √2y = 3

How to represent the above situation in linear equations in two variables ?

x + y = 200

If Sita contributed Rs. 76, then how much was contributed by Gita ?

76 - 200 ( differnce between them)

Rs. 124

Which is the standard form of linear equations x = – 5 ?

x + 5 = 0

so simple,

hope it helps and dont forget to mark me plz
