Question

plz answer me 9th 10th and 11th question answer ​

Answer 1

Answer:

9) 2940

10) 927.2

11) Equal [neither less nor more]

Step-by-step explanation:

9) 30/100 * 4200 = 3*420 = 1260

There fore 4200-1260 = 2940

10) 22/100 * 760 = 167.2

Therefore 760 + 167.2 = 927.2

11) First i.e. before the reviewer sees, the cost = 1500 + 10%

    Then after the reviewer sees, the cost = 1500 +10% - 10%

Now +10 and -10 will be cancelled and the cost would be 1500

Hence he got the same 1500 rupees that is neither less nor more
