The price of Darjeeling tea (in rupees per kilogram) is 100 + 0.10 n, on the nth day of 2007 (n = 1, 2, ..., 100), and then remains constant. On the other hand, the price of Ooty tea (in rupees per kilogram) is 89 + 0.15n, on the nth day of 2007 (n = 1, 2, ..., 365). On which date in 2007 will the prices of these two varieties of tea be equal?

A line with the equation y = px + q is reflected over the line y = x. Is the reflection of this line parallel to the line y = mx + n?
(1) m = p + 2
(2) m = 3p
1) only a is sufficient
2) only b alone is sufficient
3) both a n b combined can ans
4) data insufficient to ans Skip

both a n b are nt suffient to ans ..as it requires m=1/p (on replacing y=x and comparing the slps)..on taking and b p=1,m=3 which is nt suff
