Each 100 ohm resistance have tolerance of 5%. i.e. 5 ohm.
Total tolerance of 4 such resistances is 4 × 5 = 20 ohms.
Total resistance of combination is 4 × 100 = 400 ohms.
Tolerance of the combination will be -
Tolerance = 20 / 400 × 100 %
Tolerance = 5 %
Therefore, tolerance of the combination will be 5 %.
