A man ordered 4 pairs of black socks and some pairs of brown socks. The price of a black pair is double that of a brown pair. While preparing the bill, the clerk did a mistake and interchanged the number of black and brown pairs. This increased the bill by 50%. The ratio of the number of black and brown pairs of socks in the original order was

If the equation x^(3)+ax^(2)+bx-4=0 has two roots equal to 2, then the ordered pair (a,b) is

If (a+ib)^(2018)=a- ib then number of real ordered pairs (a,b) that are solution of the given equation is N , then [(N)/(100)] equals

Given the set A = {-2, -1,.0, 1, 2},- list the ordered pairs(a, b) on A determined by the relation ‘ a is equal to b'
