Canto 2 -
Ayodhyā-kāṇḍa
Chapter 70: Bharata Departs from Rājagṛha
Text 2.70.5

अत्र विंशतिकोट्यस्तु नृपतेर्मातुलस्य ते।
दशकोट्यस्तु संपूर्णास्तथैव च नृपात्मज॥

atra viṁśati-koṭyas tu nṛpater mātulasya te
daśa-koṭyas tu saṁpūrṇās tathaiva ca nṛpātmaja

atra = here; viṁśati-koṭyaḥ tu = the items here worth 200 million coins are; nṛpateḥ = for the king; mātulasya = for maternal uncle; te = Your; daśa-koṭyaḥ tu = items worth [not less than] 100 million coins are; saṁpūrṇāḥ = not less than; tathā eva ca = and; nṛpa-ātmaja = O prince.

O prince, the items here worth not less than 200 million coins are for the king and items worth [not less than] 100 million coins are for Your maternal uncle.

It is implied that if they had gifted the king and the prince of Kekaya equally, it would not have been a gesture of [proper] respect.
