Galvanometer To Ammeter/Voltmeter||Application of Ammeter/ Voltmeter||Real Ammeter/ Voltmeter

Assertion : In the circuit shown in figure ammeter and voltmeter are non-ideal. Why positions of ammeter and voltmeter are changed, reading of ammeter will increase while of voltmeter will decrease. Reason : Resistance of an ideal ammeter is zero while that of an ideal voltmeter is infinite.

In the diagram shown, the reading of voltmeter is 20 V and that of ammeter is 4 A . The value of R should be (Consider given ammeter and voltmeter are not ideal)
