Question

4p/5=16 solve in trail and error method​

Answer 1

Answer:

20

Step-by-step explanation:

Trial and error method : -

4p / 5 = 16

When p = 5,

4 ( 5 ) / 5 = 16

20 / 5 = 16

4 ≠ 16

When p = 10,

4 ( 10 ) / 5 = 16

40 / 5 = 16

8 ≠ 16

When p = 15,

4 ( 15 ) / 5 = 16

60 / 5 = 16

12 ≠ 16

When p = 20,

4 ( 20 ) / 5 = 16

80 / 5 = 16

16 = 16

So, p = 20
