Given that 0 < a < b < c < d, which of the following the largest ? a.(c+d) / (a+b) b.(a+d) / (b+c) c.(b+c) / (a+d) d.(b+d) / (a+c) Sol: A Explanation: Take a = 1, b = 2, c = 3, d = 4. option A is clearly true. 4. Eesha bought 18 sharpeners for Rs.100. She paid 1 rupee more for each white sharpener than for each brown sharpener.
