14 If P = 5040 then (n,r) = 1) (9,4) 2)(10,4) 3) (11,3) 4) (11, 4) 10

Locate the points: (1,1),(1,2),(1,3),(1,4).

(1)/(3)x+y=(10)/(3),2x+(1)/(4)y=(11)/(4)

Let X = { 1,2,3,4 } and R = { (1,1), (1,2),(1,3),(2,2), (3,3),(2,1),(3,1),(1,4),(4,1)}. Then R is

Find sum to infinite terms of the series 1 + 2 ((11)/(10)) + 3 ((11)/(10)) ^(2) + 4 ((11)/(10)) ^(3) +………

Denominator of 9(3)/(4) +11(1)/(2) +8(1)/(4) is

The average of 11 numbers is 10.9. If the average of the first six numbers is 10.5 and that of the last six numbers is 11.4, then the middle number is: (a) 11 (b) 11.3 (c) 11.4 (d) 11.5

If (10)^(9)+2(11)^(1)(10)^(8)+3(11)^(2)(10)^(7)+....+10(11)^(9)=k(10)^(9), then k is equal to (1)(121)/(10)(2)(441)/(100) (3) 100(4)110
