Which of the following is NOT correctly matched?
- (a)Hundru Waterfall - Subarnarekha River
- (b)Chachai Waterfall - Bihad River
- (c)Dhuandhar Waterfall - Narmada River
- (d)Budha Ghagh Waterfall - Kanchi River
Correct — D, 'Budha Ghagh Waterfall - Kanchi River' is the mismatched pair. Budha Ghagh (also called Lodh Falls), the highest waterfall in Jharkhand, is in Latehar district on the BURHA River — not the Kanchi. The Kanchi River is actually the river of DASSAM Falls (near Bundu, Ranchi). So pairing Budha Ghagh with the Kanchi River is wrong. The other three are correctly matched: Hundru Falls on the Subarnarekha, Chachai Falls on the Bihad, and Dhuandhar Falls on the Narmada.
- (a)Hundru Waterfall - Subarnarekha River — Correctly matched, so not the answer. Hundru Falls, in Ranchi district (Jharkhand), is on the Subarnarekha River.
- (b)Chachai Waterfall - Bihad River — Correctly matched, so not the answer. Chachai Falls, in Rewa district of Madhya Pradesh, is on the Bihad River (a tributary of the Tamsa/Tons).
- (c)Dhuandhar Waterfall - Narmada River — Correctly matched, so not the answer. Dhuandhar Falls at Bhedaghat (Jabalpur, Madhya Pradesh) is on the Narmada River, amid the famous marble rocks.
This is a waterfall-to-river matching question drawn mostly from the Chota Nagpur Plateau (Jharkhand) and central India (Madhya Pradesh). Hundru Falls (Subarnarekha) and Budha Ghagh/Lodh Falls (Burha River, Latehar) are Jharkhand falls; Dassam Falls, on the Kanchi River near Bundu, is a third Jharkhand fall often confused with them. Chachai Falls (Bihad) and Dhuandhar Falls (Narmada) are in Madhya Pradesh.
Three pairs are standard-atlas correct, so the trap has to be the fourth. The examiner swaps the river of one Jharkhand fall for another's: the Kanchi River belongs to Dassam Falls, but is here attached to Budha Ghagh (whose real river is the Burha). Knowing that 'Kanchi = Dassam Falls' immediately exposes option (d) as the mismatch.
- Budha Ghagh (Lodh Falls) — Latehar, Jharkhand — is on the Burha River (the state's highest waterfall), NOT the Kanchi.
- The Kanchi River (a Subarnarekha tributary) is the river of Dassam Falls, near Bundu, Ranchi.
- Hundru Falls = Subarnarekha River; Chachai Falls = Bihad River (Rewa, MP); Dhuandhar Falls = Narmada River (Bhedaghat).
- Subarnarekha and Kanchi are both Chota Nagpur Plateau rivers — an easy source of confusion.

- Swapping the rivers of nearby Jharkhand falls — Kanchi belongs to Dassam Falls, not Budha Ghagh.
- Assuming the odd-one-out must be an unfamiliar name; here the familiar Hundru/Dhuandhar pairs are the correct ones.
UPPSC/UPSC give waterfall–river (or waterfall–state) pairs and ask which is/are correctly or NOT correctly matched — anchor each famous fall to its river.
Which of the following pairs are correctly matched? Waterfalls — River 1. Kapildhara Falls : Godavari 2. Jog Falls : Sharavati 3. Sivasamudram Falls : Cauvery Select the correct answer using the code given below:
- (a) 1 and 2 only
- (b) 2 and 3 only
- (c) 1 and 3 only
- (d) 1, 2 and 3
Answer(b) 2 and 3 only
Same concept and format — matching Indian waterfalls to their rivers (Kapildhara is on the Narmada, not the Godavari), exactly the skill tested by this UPPSC pairs item.
The waterfall 'Victoria' is associated with the river
- (a) Amazon
- (b) Missouri
- (c) St Lawrence
- (d) Zambezi
Answer(d) Zambezi
Same waterfall-to-river identification skill (Victoria Falls on the Zambezi) — the world-geography counterpart of this UPPSC Indian-waterfalls question.

Dassam Falls, in Ranchi district of Jharkhand, is located on which river?
- (a)Damodar River
- (b)Kanchi River
- (c)Burha River
- (d)Barakar River
Answer(b) Kanchi River — a tributary of the Subarnarekha; this is why the Kanchi cannot be paired with Budha Ghagh.
- practice — not a real PYQ
Dhuandhar Falls, famous for the marble rocks at Bhedaghat, is on which river?
- (a)Tapi
- (b)Chambal
- (c)Narmada
- (d)Betwa
Answer(c) Narmada — Dhuandhar Falls lies on the Narmada near Jabalpur, Madhya Pradesh.
