Hi frnds..........

(a) 32 / 100 = Rs 256
.............
(b) 85/ 100* 2 = 1.7 kg = 1700 g
..........................
(c) let us consider the percent as 'x'

x / 100*40 = 5 ⇒ 40 x / 100 = 5

⇒ 0.4 x = 5 ⇒ x = 12.5%
..........
(d) S.P = rs 450
profit = rs 80

C.P = S.P - profit
= 450 - 80
= rs. 370
.............

Hope it helps....... :D
