Question

D/5=4 A. d=20 B. d= 4/5 C. d=5/4

Answer 1

The value of A =
`(1)/(16)`

The value of B =
`(1)/(16)`

The value of C =
`(25)/(16)`

The value of D =
`(5)/(4)`

Explanation:

Given as :

The following relations are as

`(d)/(5)` =4 A ...........1

d = 20 B ...........2

d =
`(4)/(5)` C ...........3

And d =
`(5)/(4)`

Now, From the above relations

Put the value of d in eq 1

∵ 4 A =
`(d)/(5)`

So, d = 5 × 4 A

Or,
`(5)/(4)` = 20 A

∴ A =
`((5)/(4))/(20)` =
`(1)/(16)`

I.e The value of A =
`(1)/(16)`

Again

From eq 2

∵ d = 20 B

Put the value of d

So,
`(5)/(4)` = 20 B

Or, B =
`((5)/(4))/(20)`

∴ B =
`(1)/(16)`

I.e The value of B =
`(1)/(16)`

Similarly

From eq 3

d =
`(4)/(5)` C

Put the value of d

So,
`(5)/(4)` =
`(4)/(5)` C

Or, C =
`(5* 5)/(4* 4)`

∴ C =
`(25)/(16)`

I.e The value of C =
`(25)/(16)`

Hence The value are

The value of A =
`(1)/(16)`

The value of B =
`(1)/(16)`

The value of C =
`(25)/(16)`

The value of D =
`(5)/(4)`
