For x∈N, x>1, and p=logxx+1, q=logx+1x+2 then which one of the following is correct?
kl>k+1l+1 for (k,l) > 0 and k > l
Let k = x+1 and l = x
Therefore, x+1x>(x+1)+1(x)+1
(x + 1) > x
Therefore, log(x+1)log(x)>log(x+2)log(x+1)
⇒logxx+1 >logx+1x+2
A rectangular lawn of dimensions 80 m x 60 m has two roads each 10 m wide running in the middle of the lawn, one parallel to the length and the other parallel to the breadth. What is the cost of traveling the two roads at Rs.3 per sq m ?
Area = (l + b – d) d
= (80 + 60 – 10)10
=> 1300 sq.mts
=> 1300 x 3 = Rs.3900
