Question

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 1

Answer:

Step-by-step explanation:

(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 yRead more on Sarthaks.com - https://www.sarthaks.com/858973/both-vary-inversely-each-other-when-which-following-possible-pair-corresponding-values
