1.	Both x and y vary inversely with each other. When x is 10, y is 6, which of the following is not a possible pair of corresponding values of x and y?(a) 12 and 5 (b) 15 and 4 (c) 25 and 2.4 (d) 45 and 1.3
Answer» (d) 45 and 1.3 Explanation: Since x and y vary inversely, so xy = k (constant) Putting the value of x and y, we get; 10×6 = 60 Now if we observe the options available; Option (a) – 12 and 5 – 12×5 = 60 Option (b) – 15 and 4 – 15×4 = 60 Option (c) – 25 and 2.4 – 25×2.4 = 60 Option (d) – 45 and 1.3 = 45×1.3 = 58.3 Therefore, option (d) is not a possible pair of corresponding values of x and y

Both x and y vary inversely with each other. When x is 10, y is 6, which of the following is not a possible pair of corresponding values of x and y?(a) 12 and 5 (b) 15 and 4 (c) 25 and 2.4 (d) 45 and 1.3

Answer»

(d) 45 and 1.3

Explanation:

Since x and y vary inversely, so

xy = k (constant)

Putting the value of x and y, we get;

10×6 = 60

Now if we observe the options available;

Option (a) – 12 and 5 – 12×5 = 60

Option (b) – 15 and 4 – 15×4 = 60

Option (c) – 25 and 2.4 – 25×2.4 = 60

Option (d) – 45 and 1.3 = 45×1.3 = 58.3

Therefore, option (d) is not a possible pair of corresponding values of x and y
