Question

friends please solve cleared explanation. ​

Answer 1

Answer:

Step-by-step explanation:

Let's assume G is the number of glasses delivered intact. then,

       3G = the amount earned.

Let's assume B is the number of glasses broken.

Then,

         9B = the amount forfeited

         3G - 9B  = 240

         9B = -240

         G+B = 100

         3B/128   =    300/60

B = 5, G = 95

Answer 2

Answer:

5

Step-by-step explanation:

let x be the amount of glass safely delivered

so broken glass will be 100-x.

now for each glass delivered safely, she pays 3 paise or 0.03rs.

and for each broken glass she cuts 9 paise or 0.09rs.

hence total amount to be earned will be

amount paid for delivered glass - amount cut for broken glass.

=> x*0.03 - (100-x)*0.09 = 2.40

multiplying both sides by 100

3x - (100-x)*9 = 240

3x+9x -900 = 240

12x=1140

x=95

no of glass safely delivered is 95

hence broken glass count is 100-95=5
