The Ganges River is one of India's major river systems, originating from the Gangotri Glacier and flowing through northern India. It has numerous tributaries that contribute to its flow. Let's examine the options:

Gandak: This river originates in Nepal and joins the Ganges near Patna in Bihar. It is a left-bank tributary of the Ganges.

Ghaghra: Also known as the Karnali, it originates in Tibet and flows through Nepal and India, joining the Ganges near Chapra in Bihar. It is a major left-bank tributary.

Yamuna: This is the longest and most significant tributary of the Ganges. It originates from the Yamunotri Glacier and meets the Ganges at Prayagraj (Allahabad). It is a right-bank tributary.

Satluj: The Satluj (or Sutlej) River originates in Tibet and is one of the five rivers that give Punjab its name. It is a tributary of the Indus River, not the Ganges. It joins the Chenab River in Pakistan, which eventually flows into the Indus.

Therefore, the river that is not a tributary of the Ganges is the Satluj, as it is part of the Indus River system.
