left with her ?​

Answer 1

Answer:

4. -26

5. -225

6. Rs. 56

Step-by-step explanation:

4. Let the numbers be x and y.

given- x.y= -286        (1)

x=11

put x in equation 1

11(y)= -286

y= -286/11

y= -26

5. let number be x.

given- x/15= -15

ie x=15(-15)

x= -225

6. total amount= rs 245

english book price= rs 85

math book price= rs 110

pen price= rs 15

discount = rs 21

total money spent = rs 85+110+15 = rs 210

after discount = rs 210-21 = rs 189

money left with her= rs 245 - 189

= rs 56
