Marks: +1, -0

If (n) denotes the greatest integer and [n] denotes the smallest integer where n is any real number, then

\ (1 \ {1}/{5} ×[1 \ {1}/{5}\ ]-\ (1 \ {1}/{5}\ )+\ [1 \ {1}/{5}\ ]+(1.5)

Solution:

(2)

(1{1}/{5}) × [1{1}/{5}] - (1{1}/{5}) ÷ [1{1}/{5}] + (1.5)

=(1.2) × [1.2] - (1.2) ÷ [1.2] + (1.5)

=2 × 1 - 2 ÷ 1+ 2 = 2 - 2 + 2 = 2
