CAT Question of the Day Let N be the number of ways in which 2010 can be written in the form,
2010 = 1000a3 + 100a2 + 10a1 + a0, where ai, for 0 ≤ i ≤ 3, is an integer and 0 ≤ ai ≤99.
An example of such representation is, 2010 = 1 × 103 + 9 × 102 + 11 × 101 + 0 × 100
Find N.

Tip of the Day DI calculations can get tedious. Learn to round off the value to the nearest integer before working on the next step. Last year's Question of the day (16-Dec-11) ABCD is a parallelogram of area = 20 cm2. P lies somewhere within ABCD. Find the value of A(Δ PAB) + A(Δ PCD) if PA = 2 cm and PC = 12 cm.
