Question 1
Both u and v vary directly with each other. When u is 10, v is 15, which of the following is not a possible pair of corresponding values of u and v?
(a) 2 and 3
(b) 8 and 12
(c) 15 and 20
(d) 25 and 37.5
Please scroll down to see the correct answer and solution guide.
Right Answer is:
SOLUTION
Since, u and v vary directly, i.e.,
uv= k (constant)
If u =10 and v =15, then,
uv=1015=23
In option (b), 812=23
In option (c), 1520=34
In option (d), 2537.5=23
So, option (c)is not a possible pair of corresponding values of u and v.
Hence, option (c) is correct
