Question

Statement 1 : Every four months the price of petrol increases at the rate of Rs 7 per litre. Taking price of petrol in December 2019 as x and the price of petrol in December 2020 as y  Statement 2: Due to continuous rise in the petrol price people are shifting towards CNG Whose price increases at the rate of Rs 5 per litre in a year. So give answer of the question by reading the above statements. 1. According to statement 1,the linear equation showing amount spent on petrol in December 2020 is A) x = y+21 B) x= 7-y C) y=x+21 D) x =7+y 2. If x =3,find the value of y A) 9 B) 24 C) 4 D) 10 3. According to statement 2, the linear equation taking price of CNG in December 2019 as ‘a’ and in December 2020 as ‘b’ is A) b= a-5 B) a= b-5 C) b=a+5 D) 2b=a+5 4. If a= 6, Then find the value of b A)10 B)11 C)12 D)8 5. How many solutions does a linear equation in two variables have. A) 1 B) 2 C) infinitely many D) no solution​
