Question

plz tell me fast solve it​

Answer 1

Answer:

d)

Step-by-step explanation:

that is 15 and 20 this is not a possible pair for it

Answer 2

x = 8 = 4 x 2

y = 12 = 4 x 3

$\frac{x}{y} = \frac{4 \times 2}{4 \times 3} \\ \frac{x}{y} = \frac{2}{3} \\ 3x = 2y$

now, comparing (a)

for (x, y) = (10, 15)

3x = 3 x 10 = 30

2y = 2 x 15 = 30

this satisfies 3x = 2y

Hence, 10 and 15 could be the corresponding values of x

now, comparing (b)

for (x, y) = (2, 3)

3x = 3 x 2 = 6

2y = 2 x 3 = 6

this satisfies 3x = 2y

Hence, 2 and 3 could be the corresponding values of x

similarly, verifying all the options we see that (c) is correct but (d) is not

hence, the correct answers are (a), (b) and (c)
