Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

7 - i ) 96/150 × 100 = 64 %

7 - ii ) 5kg = 5000g.

Let the percentage be x.

Therefore, ATQ:

x/100*5000=200

50x = 200

x = 4

Answer = 4%

7-iii) 1 l = 1000ml

fiven: 2 l

∴ 2 l = 2 * 1000 = 2000ml

To find: %

250/2000*100 = 12.5%

8) 4 percent *3600

(4/100) * 3600 = 144

9)16% of x=72

16/100×x=72

x=72×100/16

x=450.
