+E=10;// Volts
+R=50;// Unstrained gauge resistance(Ohms)
+Gain=100;// Amplifier gain
+Vo=1.5;// Output Voltage
+
+// Solution
+
+// Using the formula: Vo=E*(Delta_R/R)*gain
+
+Delta_R=Vo*R/(E*Gain);// Change in resistance
+

+// The answer mentioned in the textbook is incorrect as R=50 Ohms and not 100 Ohms.
