Answer 7

There are five boxes in a cargo hold.

The wt of the first box is 200 kg,

2nd is 20%higher than the wt of the 3rd: 200(1.25)(1.2)

3rd whose wt is 25% higher than the wt of the first box: 200(1.25)

The 4th box is 350 kgs and is 30% lighter than the fifth box.

350 = f(.70)

find the difference In the avg wt of the heaviest 3 and the lightest 3

200
300
250
350
500

(200+300+250)/3 - (350+500)/2

Answer 8

pfft, 3 and 3 ...

Answer 9

133.3 so we might be interpreting the question incorrectly, or they simple gave a wrong solution

Answer 10

this one
book gave hint
(350+500)-(300+200)=350

and
350/3=116.66

Answer 11

isnt the 300 the common between them?

Answer 12

(a+b+c) - (x+y+c) = a+b-x-y

Answer 13

heaviest 3 .... (500 + 350 + 300) / 3 = 1150/3 = 383.33
lightest 3 ... (200 + 250 + 300) / 3 = 750/3 = 250
383.33 - 250 = 133.33 ...oops that didn't help

Answer 14

i saw a solution manual say 0-2 = 4 so im not impressed with book solutions

Answer 15

Answer 16
