Answer 1

Answer:

Step-by-step explanation:

solution 5

given cost of 3 dozens (ie 36 oranges) = 54 rs

cost of 1 orange = 54/36 rs

cost of 1 orange = 3/2 rs

cost of 8 oranges = 3/2 * 8

cost of 8 pranges = 12 rs    answer

solution 6

in short

60 km of distance covered in =  1 hr 30 mins or 1.5 hrs

1 km of distance covered in = 1.5/60

100 km of distance covered in = (1.5*100)/60 hrs

                                                   = 15/6

                                                   = 2.5 hrs     answer

solution 7

given l ∝ w

where l = expension

          w = weight

l = k*w

where k = proportionality constant

then k = l/w

condition 1

l = 1.4 cm

w = 75 kg

k = 1.4/75.............. eq 1

condition 2

l = 9.8

k = 1.4/75

then

w =  l/k

w = (9.8/1.4)*75

w = 7*75

w = 525 kg    answer
