SOLUTION :
Temperature coefficient of resistance of silver “alpha” is 0.0038 per ºC .
Resistance increases with increase in temperature and it follows the following formula :
R = Ro ( 1 + alpha * temperature difference)
=> R35 = 4 ( 1 + 0.0038 * (35 - 21))
=> R35 = 4.2128 Ω = 4.2 Ω approx. (ANSWER).
