Question
21 out of 25
 

What are the values of x and y that satisfy both the equations?



A x = 2, y = 5
B x = 2.5, y = 6

C x = 3, y = 5
D x = 3, y = 4

E x = 5, y = 2

Ans. E

Equation (ii) can be written as

0.6x = 3, so, x = 5 and 0.4y = 4/5, hence y = 2.

If we put the values of x and y in first equation these values satisfy the first equation also.

So the answer is x = 5, y = 2
